Tips: Steps for installing digital panel meter in the field
- Install sensor: It is necessary to adjust the sensor installation correspondingly under the assistance of the field staff and according to the condition of the site. There is a need for horizontal installation and also a need for bottom-up installation. All gaskets should be in the required position. The situation of squeezing film and improper sealing should not occur.
- Wiring: Connect all sensors with digital panel meter correctly. The signal should be outputted and received correctly. Besides, the data of digital panel meter and sensors should be one-to-one correspondence.
- Debugging: All the pressure and liquid level transmitter should adjust to zero, reset parameters. In order to ensure the display of the digital panel meter in line with sensors. The upper and lower alarm value should be set according to the requirements of the site and connected to the PLC.
- Site validation: In the field inject required medium into the storage tank. The numerical value of the digital panel meter should be corresponded with the actual one. There should be no leakage in the installation place of the sensor and the temperature is displayed correctly.
Single channel digital panel meter can cooperate with displacement sensors, linear position sensors, potentiometers, etc. 16-bit A/D converter, zero clearing at any time.
