The loadcell mounts are comprised of a spring element on which the strain gauges are placed. The spring elements are sturdy and minimally elastic, as they made of steel or aluminum. According to the name spring element, the steel is minimally deformed under the pressure of a load, and then returns to its initial, starting position, elastically responding to every load. The minutely small changes are easily acquirable by the strain gauges. The final deformation on the strain gauge is eventually interpreted by the analysis of electronics to calculate the weight.

A process automation, or simply a temperature transmitter, is an electrical system that incorporates the work of a control or measuring instrument into a single device. It is, therefore, a mixture of both types of instruments, and is therefore simultaneously flexible, reliable, and effective. You should expect a lot of elements to be protected by temperature transmitters, including those that cannot protect control devices and temperature sensors when used in isolation. Until sending it to the control room or automation solutions, it not only tests the temperature, but also amplifies it and transforms it into signals. The use of industrial automation has so many practical advantages, including its ability to maintain measurement integrity and to convert low-level signals to standard signals recognised by control and monitoring systems. EMC is New Zealand’s largest manufacturer of Belt Weighers and Weighfeeders; something we’ve been proudly doing for almost 50 years.

The temperature instruments or simply temperature transmitter is an electrical device that brings the functioning of a control or measurement instrument together in a single device. So, it is a combination of both types of instruments, and is thus versatile, effective, and efficient at the same time. You can expect temperature transmitters to cover a lot of elements, even the ones which control devices and temperature sensors can't cover when used in isolation. At EMC, we supply a very wide range of Endress+Hauser temperature instruments suitable for all industrial facilities and processing plants. Their products include unique features such as self-calibration and tool-free calibration designed for hygienic applications. The E+H range includes modular thermometers, compact thermometers, measurement inserts, thermowells, and transmitters.

Metallic cell: The operating pressure deflects the metallic process isolating diaphragm and a fill fluid transfers the pressure to a resistance bridge.  The pressure-dependent change in the bridge output voltage is measured and evaluated.

The level control is important for many reasons. Too much or too little level in a container can be detrimental and so it needs to be monitored and controlled, with alarm activating to alert people that something is wrong or that they need to do something. An example of the need for control and alarms is in a sewer system where the storm water collection system and sewer system are separate. In the event of heavy rain storms, water can get in to and overwhelm the sewer system, causing the sewage to overflow into the streets. This is a potential health threat that can result in fines for the company responsible. The sewage can also cause damage to properties which the company would have to pay out to make good. An alarm that gives early warning can give the company enough time to do something about the situation. Another commercial use of liquid level control and alarms is to warn of an overflow in oil tanks. Endress+Hauser is not restricted by a limited number of measurement principles and can, therefore, offer the method best suited to your particular application in either liquids or bulk solids. We’ll carefully listen to your requirements and then offer the best suited and most cost-effective solution. We also offer onsite assistance with commissioning to ensure the instrument is installed correctly and performing as required.

Electromagnetic

Proven flow measuring technology for all electrically conductive liquids in every industry.

Electromagnetic flow meters have been used throughout industries for more than 60 years.
These meters are applicable for all conductive liquids, such as water, acids, alkalis, slurries, and more. Typical applications are monitoring of liquids, filling, dosing, and precise measurement in custody transfer. Endress+Hauser has manufactured more than two million mag meters since 1977.
Electromagnetic flow measuring principle:
Faraday's law of induction states that a metal rod moving in a magnetic field induces an electrical voltage. This dynamo principle also governs the way electromagnetic flow meters work. As soon as the electrically charged particles of fluid cross the artificial magnetic field generated by two field coils, and the electric voltage is induced. This voltage, tapped by two measuring electrodes, is directly proportional to the velocity of flow and thus to the flow volume.
Benefits:

Coriolis

Simultaneous measurement of mass flow, density, temperature and viscosity

Simultaneous measurement of mass flow, density, viscosity, and temperature opens entirely new perspectives for process control, quality assurance, and plant safety.
Coriolis flow measuring principle:
Each Coriolis flowmeter has one or more measuring tubes that an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid's inertia. Two sensors detect this change of the tube oscillation in time and space as the "phase difference". This difference is a direct measure of the mass flow.

In addition, the fluid density can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also registered to compensate for thermal influences. The process temperature derived from this is available as an additional output signal.

Benefits:

Universal measuring principle for liquids and gases

Multivariable measurement - simultaneous measurement of mass flow, density, viscosity, and temperature

High measuring accuracy: Typically, ±0.1%, optionally ±0.05% with special
calibration

No inlet/outlet runs required

Measuring principle independent of the physical fluid properties and the flow profile

For additional information please feel free to contact our team directly.

Vortex

Robust and universally applicable for liquids, gases, and steam

Vortex flowmeters are used in all industries to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemical industry for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, demineralised water, solvents, oils, boiler feedwater, condensate etc.
Vortex flow measuring principle:
The measuring principle is based on the fact that turbulence forms downstream of obstacles in the flow. Inside each vortex flowmeter, a bluff body is therefore located in the middle of the pipe. As soon as the flow velocity reaches a certain value, vortices form behind this bluff body, are detached from the flow, and transported downstream. The frequency of vortex shedding is directly proportional to the mean flow velocity and thus to volume flow. The detached vortices on both sides of the bluff body generate alternately a local positive or negative pressure that is detected by the capacitive sensor and fed to the electronics as a
primary digital, linear signal.

Thermal Mass

Direct mass measurement of industrial gases, compressed air, and aqueous fluids

Whenever high turndown or low-pressure losses are important in gas metering applications in any industry, thermal mass flow meters offer a real alternative to traditional measuring techniques, whether for process control, consumption and supply monitoring, detecting leaks, or monitoring distribution networks. Using insertion versions, it is also possible to measure gas flows in very large pipelines or in rectangular ducts.
Thermal mass measuring principle:
This measuring principle is based on the fact that heat is drawn from a heated body when a fluid flows past. A thermal flow meter contains two PT100 temperature sensors for this purpose. One sensor measures the current fluid temperature as a reference. The second sensor is heated and has a constant temperature differential relative to the first sensor at "zero flow". As soon as the fluid begins to flow in the measuring tube, the heated temperature sensor cools off due to the fluid flowing past - the higher the flow velocity, the greater the cooling effect. The electric current required to maintain the temperature differential is thus a direct measure of mass flow.
Benefits:
For additional information please feel free to contact our team directly.

Ultrasonic

Versatile and economical flow measurement of gases and liquids

Using ultrasonic waves, the volume flow of a wide variety of gases and liquids can be measured reliably, independent of electrical conductivity, pressure, temperature or viscosity.

Ultrasonic flow measuring principle:
Swimming against the flow requires more power and more time than swimming with the flow.

This simple fact is the basis for ultrasonic flow measurement according to the "differential transit time" method. This method uses two sensors, set opposite each other in the measuring tube. Each sensor can alternatively transmit and receive ultrasonic signals, while simultaneously measuring the signal transit time. As soon as the fluid in the tube starts to flow, the signals are accelerated in the direction of the flow but delayed in the opposite direction. This differential transit time, measured by the two sensors, is directly proportional to the flow rate.

Flow Switches

Calorimetric Flow Switches

Safe monitoring of flowrates with no moving parts

Calorimetric (Thermal) Flow Switches offer the benefit of no moving parts and practically no pressure loss. They are used for monitoring and displaying the relative mass flow rates of liquid media in the range from 0.03 to 3 m/s . Endress+Hauser supplies the following models for standard and hygienic applications:

Flowphant T DTT31 − with threaded connections or compression fitting

Flowphant T DTT35 − with process connections for hygienic applications

Measuring principle:
The Flowphant measures the mass flow of a liquid medium using the calorimetric measurement method. The calorimetric measuring principle is based on the cooling of a heated temperature sensor. Heat is removed from the sensor by forced convection due to medium flowing by. The extent of this heat transfer depends on the flow velocity of the medium and the difference in temperature between the sensor and the medium (King's Law). The higher the flow velocity or the mass flow of the medium, the greater the temperature sensor cooling.
Applications:

Monitoring of cooling water circuits of pumps, turbines, compressors and heat exchangers

Monitoring of pump functions

Leak monitoring in process pipes

Monitoring of lubrication circuits

Filter monitoring in the beverages industry

Benefits:

Virtually zero pressure loss

FieldCare for quick configuration and reliable storage of device settings

Optional: 4 to 20 mA analogue output for outputting the flow as a percentage

Optional: second switch output or 4 to 20 mA analogue output for temperature monitoring

Onsite function check and process information with a digital display on the device

Top housing section which can be rotated 310° and rotatable display mean measured values can be read in all installation positions
