Flow is calculated as follows Ta= L / ( C + V )
Ta= L / ( C + V )
Tb= L / ( C – V )
V=L/2(1/Ta-1/Tb) Q=V*A
(Volumetric flow rate = Flow velocity * Cross-sectional vector area)
V: Fluid flow rate (0 to 5 m/s)
C: Velocity of sound (500m/s in water)
L: Sonic transfer distance
Replace Parts & Testing :
Replace Teflon tube to confirm the output flow is normal。
- Replace Motor adapter to Confirm whether the Output Voltage flow is normal。
- Cleaning, lubricating and maintenance of Motor gear。
- High Pressure Cleaning of Ultrasonic flow detector。
- Confirm the Converter parameter setting。
Use a voltage regulator Pump attached to the Controller to measure the amount of voltage flow is stable 。
