The stability of the power supply affects the performance index of the transmitter, and its error is controlled to be less than one-fifth of the allowable error of the transmitter. For products with special power supply requirements, a special power supply must be connected. 2. The signal line of the transmitter should adopt a shielded cable to prevent electromagnetic wave interference. 3. Connect the transmitter according to the correct wiring method, and the power-on time should be fifteen to thirty minutes. 4. If the transmitter is installed in a pool, a water tower, etc., its probe can be immersed in the bottom of the water, away from the position where the water velocity is too fast. 5. The liquid level transmitter used in the occasions with large fluctuations such as submersible pumps is installed using the method of inserting the steel pipe. The steel pipe should be fixed firmly, a hole should be opened on the steel pipe at intervals, and the position of the steel pipe should be far away from the water inlet and outlet. 6.
