1.Perform sanitary cleaning once a week to keep the transmitter and its accessories clean.
2.Check the pressure-taking pipeline and valve joints for leakage once a week. If there is any leakage, it should be dealt with as soon as possible.
3.Monthly check that the transmitter components are intact, no serious corrosion or damage; the nameplate and identification are clear and correct; the fasteners must not be loose, the connectors are in good contact, and the terminal wiring is firm.
4.Check the on-site measurement circuit once a month, including whether the input and output circuits are intact, whether the circuit is disconnected, short-circuited, and whether the insulation is reliable, etc.
5.Check the accuracy of the zero point and display value of the meter every month, and the zero point and display value of the transmitter are accurate and true.
6.Perform regular calibration according to the transmitter calibration cycle.
7.Periodically drain, drain or vent the transmitter.
8.The transmitter with isolation fluid in the source pipeline or measuring element is regularly filled with isolation fluid.
9.Regularly purge the pressure guiding tube of the easy-blocking medium.
10.When the transmitter is disabled for a long time, it should be turned off once.
11.When the transmitter is in operation, its housing must be well grounded. The transmitter used to protect the system should have measures to prevent power failure, short circuit, or output open circuit.
12.In the winter season, check that the instrument's source pipeline is well insulated and heat tracing, so as to avoid the source pipeline or the measuring element of the transmitter from being damaged by freezing.
