The steam booster heat meter is a high-precision steam booster heat meter. It is integrated with professional digital display regulator relative signal converter to maintain the total flow data signal transmission, total flow brand digital display regulator and flow display information. This kind of controller market high-precision digital display regulator is applied to the detection system of gas, gas, liquefied gas, etc.
When the pipeline is filled with material, use a digital multimeter to accurately measure the resistance value in the middle of the terminal blocks A, B and C. The resistance in the middle of the A- C and B- C should be about the same. If the difference is about 1 times, it will be the metal electrode seepage, accurate measurement of the surface of the tube or the terminal has condensed water adsorption. Under the condition of dry lining, the vapor turbine flowmeter shall use M meter to measure the grounding resistance between the A- C and B- C (which shall exceed 200M). Then use a digital multimeter to accurately measure the resistors of the terminals A and B and the two metal electrodes in the accurate measurement tube (should be connected with a short circuit fault). If the grounding resistance is not large, indicating that the metal electrode seepage, the full set of steam flowmeter should be repaired. If the insulation layer drops obviously but there is still about 50M and the process 1 and inspection results are normal, the moisture return on the surface of the tube will be accurately measured, and the inside of the shell can be air-dried by a hot air blower. The gas turbine flowmeter uses a digital multimeter to accurately measure the resistor between X and Y. If it exceeds the 200, the magnetic ring of the excitation regulator and the outgoing wire will lead or touch poorly. Disassemble the terminal block for inspection. The grounding resistance between X, Y and C shall be checked by the vapor turbine flowmeter, which shall be about 200M. If it is obviously reduced, warm air shall be used to dry the inside of the shell. In actual operation, the decrease in the dielectric strength of the magnetic coil will cause the measurement deviation to expand and the instrument panel output data signal to be unstable. If it is judged that the controller has common faults, please contact the manufacturer. Generally, it cannot be handled on the spot and needs to be returned to the factory for maintenance.
