Introduction
ESEGAS Ultrasonic Flow Meter LEUF-200 for Flue Gas Application is to measure the flow rate of the gas; it can also calculate and output the volumeflow rate according to the flow rate and the flue size; if you input the temperature and pressure of the flue gas, you can calculate the flow rate under the standard conditions.

The range of application of the system is as follows:
Chemical plants, pharmaceuticals, grain and dairy industry processes.
Plastics processing and refining processes
Utility plants, eg power plants and boiler emissions.
Waste treatment, eg waste incineration plant emissions.
Basic industries, eg chemical, iron and steel industries.
The transmit/receive probe consists of a piezoelectric ultrasonic generator and a receiver. The acoustic pulse and the direction of gas flow to form the angle α, the ultrasonic and gas flow direction countercurrent and downstream transmission time is determined by the angle α and the gas flow velocity v, the larger the difference between the ultrasonic transmission time, the faster the gas flow rate, temperature and pressure fluctuations can cause the ultrasonic propagation speed changes, but in this measurement method, does not affect the calculation of the gas flow rate.
The Ultrasonic Flow Meter for Flue Gas Application measures the flow rate of gases discharged from ducts, flues, exhaust gases and flues; it can be used in both pure and raw gases; ie in closed circuits as well as in open gas circuits.
The Ultrasonic Flow Meter performs gas flow rate measurements by measuring the lag time of ultrasonic pulses. Meanwhile, we mount the transmitter/receiver probe on the side of the stack. And we orient the transmitter/receiver probe at a certain angle to the direction of gas flow.
Features
Integrating two probes, a control and calculation unit, provides a wealth of interfaces. We can expand the interface to different signal inputs and outputs, and can meet the needs of different occasions under the application.
