| Pay Special Attention to Installing Site |
| |
| ¢ Axial line of the measuring electrode must be horizontal |
¢ Meter pipe must be filled with the measured fluid fully
¢ Specify the minimum length of the straight pipe 5D (D=inside diameter of the flowmeter) for upstream, 3D for downstream. In order to install and remove flowmeter conveniently, suggest a flexing pipe be used behind the flowmeter
¢ Flowing direction must be conformed to the indicating arrow on the flowmeter
¢ Negative pressure in pipe line will destroy the liner of flowmeter
¢ No strong magnetic field and radio around the meter
¢ To install and maintain meter conveniently, there should be enough space around the meter
¢ A fixed bracket be equipped at both side of the flowmeter if the pipe vibration existence
¢ The distance of the meter to mixing point should be 30D (D=inside diameter of the flowmeter) if the measured fluid is mixed
¢ To convenient cleaning and maintenance, a by-pass pipe should be equipped, as well as ensure the condition of straight pipe 5D for upstream and 3D for downstream
¢ When install meter, tight the bolts of the flange with a average torque force to prevent liner from broken, using special torque wrench
¢ ? Meter be installed in the lower pipe or upward vertical pipe, avoid installing at the highest point in pipeline or in the downward vertical pipe
|
 |
| ¢ Install where pipe is
rising |
 |
| ¢ For
draining pipe, meter be installed at the lower
point |
 |
| ¢ If the differential fall of the pipe is >5m, a draining valve for gas be installed in the downstream of the meter |
 |
| ¢ Control valve and cutoff valve be installed in
the downstream of the meter instead of in the
upstream
|
 |
| ¢ The meter must be installed at the outlet of
the pump, but not at the inlet
|
 |
¢ Meter installed in well
1. Inlet 2. Overflow-tube
3. Inlet grid 4. Cleaning hole
5. Flowmeter 6. Duct
7. Outlet 8. Draining valve
9. Draining valve for dirties
