This mass flow meter for compressed air marks a real technological breakthrough in air flow measurement. It allows to highlight your compressed air consumption. Its objective is to make important energy savings by identifying the consuming networks and the compressed air leaks. With a flawless accuracy, this mass flow meter allows you to control and adjust the parameters of your air compressor.
Efficient use of energy helps control costs and reduce the negative impact on the environment.
Among industrial utilities, compressed air represents up to 20% of the total energy budget of a factory.
The need for this gas is one of the largest electrical consumption items, but the price of this energy can be controlled.
Flowmeters are used in compressed air systems to provide a measure of air flow rate. Compressed air systems typically have high leakage rates, high start-up and shut-down times, and other problems that lead to losses and therefore waste. Industrial air mass flowmeter measurement helps to identify areas of excessive use and to better manage the overall flow rate of the compressed air system.
Measuring, analyzing and communicating key plant performance indicators can therefore help raise awareness of effective practices, and thus help control costs, ensure better protection of equipment and achieve savings.
Fuji Electric flowmeters for compressed air consist of two ultrasonic sensors installed on either side of the meter inlet and outlet.
As the liquid flows, the ultrasonic waves propagate diagonally from the upstream sensor to the downstream sensor and back in the pipe where the mass flow meter is positioned.
With this technique, the waves are "carried" by the fluid, in the other, they are "braked".
It therefore takes a different time to pass from the upstream sensor to the downstream sensor. This difference is proportional to the velocity and therefore the flow rate of the fluids.
This time difference allows to detect the fluid flow velocity and to calculate the volumetric flow rate according to the cross section of the flow meter and the Measuring principle - how to measure a compressed air flow rate FWD screenflow velocity measurement.
The number of measuring points on compressed air flowmeters must be adapted to the size and use of the system.
The FWD-A ultrasonic flowmeter is an alternative to the thermal mass flowmeter for flow measurement, as it doesn't clog up and is highly resistant to oil-contaminated compressed air. The meter even works in the presence of water droplets (dew point).
Thanks to the combined measurement of flow, temperature and pressure, this ultrasonic compressed air flowmeter provides clear data on compressed air consumption and eliminates any uncertainty in final measurements.
