Sections that must be checked
a. Pressure Transmitter- Pressure Transmitter calibration should be done, to ensure that the device is working properly.
b. Gate Valve
- Checking function of gate valve to avoid clogging the drain hole. Because disfluencies can reduce the flow of water pressure.
 |
| Pressure Transmitter Unit and Pipe Installation |
- Checking function of differential pressure pipe installation to avoid clogging the drain hole. Because disfluencies can reduce the flow of water pressure.
 |
| Differential pressure Transmitter Pipe Installation |
- Adjustment values / parameters are the same as the results of the calibration has been done.
- Substation with I/O Module To ensure that the module is still processing the input from the transducer and feeding into the MDU.
