What is the purpose of the pulse value in ultrasonic flowmeters?
Thread Content
Recently, the company acquired several new ultrasonic flowmeters; previously, turbine flowmeters were used. The calibration certificate specifies an instrument coefficient of 4500 1/m3. For turbine flowmeters, usually one pulse corresponds to 1 cubic meter, or 10 pulses correspond to 1 cubic meter, and the volume is then calculated by counting the pulses. But why is the pulse value for ultrasonic flowmeters so high? Moreover, from a measurement principle perspective, the volume flow rate is determined by calculating the speed of the gas, which is different from the volume calculated based on the number of pulses. Then why is an instrument coefficient K value specified?
Are you sure it’s 4500 1/M3? It should be 4,500 pulses per cubic unit, right?
That is the equivalent of the pulse output from the flow meter.
It’s 4,500 pulses per cube
So what’s the problem? Doesn’t that indicate high precision?
