What is Q1, Q2, Q3, Q4 and R for ultrasonic water meter
Q1 Minimum flow rate Q2 Transitional flow rate Q3 Permanent flow rate (working flow) Q4 Overload flow rate Make sure that the maximum flow that will pass through the meter never exceeds Q3. Most water meters have a minimum flow (Q1), below which they cannot provide an accurate reading. If ...Read more -

The principle and application of transit-time ultrasonic flow meter?
A transit-time difference type ultrasonic flowmeter is measured using A pair of transducers (sensors A and B in the figure below), which alternately (or simultaneously) transmit and receive ultrasonic waves. The signal travels faster upstream than upstream in the fluid, ...Read more -
What is difference between reading accuracy and FS accuracy of the flow meter?
The reading accuracy of the flowmeter is the maximum allowable value of the relative error of the instrument, while the full scale accuracy is the maximum allowable value of the reference error of the instrument. For example, the full range of the flowmeter is 100m3/h, when the actual flow is 10...Read more
