How to debug Shanghai Kent flowmeter? (No instruction manual)
The core parameter of a vortex flowmeter is the vortex coefficient. It is necessary to confirm the specific value and unit of the vortex coefficient, and if necessary, perform unit conversion to meet the set requirements. If the vortex flowmeter has built-in density measurement function, especially with temperature and pressure compensation function or can directly set density compensation, its density compensation setting should be checked for accuracy. For example, when measuring steam, it is usually necessary to perform temperature and pressure compensation to confirm whether these compensation settings are correct. According to the instructions, the problem is usually not significant. However, if the measurement results are inaccurate, it is necessary to consider the surrounding environmental factors, such as whether equipment that may cause vibration such as welding affects the pipe, whether the length of the straight pipe section meets the requirements, and whether the flow rate is within the measurement range. For the debugging of flow meters, the most crucial thing is to ensure that all parameter settings are accurate, while also paying attention to the influence of external environmental factors to ensure the accuracy of measurement results. If the vortex coefficient is not set properly or the density compensation is not configured correctly, it may lead to measurement data deviation. Therefore, it is recommended to carefully check and adjust the parameters of this finger touch to ensure that they meet actual needs. In addition, the measurement range and length of the straight pipe section of the vortex flowmeter are also very important. En
2. E2 fault of Shanghai Kent electromagnetic flowmeter
The E2 fault code displayed by Shanghai Kent electromagnetic flowmeter usually points to incorrect parameter settings of the converter or hardware problems of the circuit board.
. 1. Troubleshooting of Converter(1) Parameter Setting Error This is the most common reason, such as the inner diameter of the pipeline, fluid density, or flow unit setting not matching the actual working conditions. Please refer to the equipment installation drawings and verify one by one whether these basic parameters are entered correctly. In addition, check whether the direction of the arrow on the sensor housing is consistent with the actual flow direction of the fluid; If the installation direction is opposite, the "reverse measurement" function needs to be enabled in the converter menu to correct it.
(2) If the parameters are confirmed to be correct, it may be a hardware failure of the circuit source circuit board. The manifestation is usually abnormal display or output signal failure. The damp environment may cause internal moisture and short
