High pressure electromagnetic flowmeter is composed of high pressure electromagnetic flow sensor and intelligent converter produced with proprietary technology and special process. It is specially used to measure the volume flow of conductive liquid or liquid-solid two-phase medium such as mud, cement slurry and high-pressure water injection under high pressure conditions in geological, petroleum exploration and oilfield systems.Selection of Installation Environment for High Pressure Electromagnetic Flowmeter1. Keep away from equipment with strong electromagnetic field, such as large motor, large transformer, etc.2. The installation site shall be free from strong vibration and the pipeline shall be firmly fixed. The ambient temperature should not change much.3. The installation environment shall be convenient for installation and maintenance.4. The installation position shall ensure that the pipeline is always filled with the measured fluid.5. Select a place where the fluid flow pulse is small. That is, it should be far away from local resistance parts such as pumps, valves and elbows.6. When measuring two-phase (solid, liquid or gas, liquid) fluid, the place where phase separation is not easy to occur shall be selected.7. Negative pressure at the measuring position shall be avoided.8. The diameter or perimeter of the pipe to be side is easy to measure, and the ovality should be small. B. The distance L between the two poles is proportional to the average flow velocity of the fluid.Maintenance, repair and common troubleshooting of high-voltage electromagnetic flow meterThe flow of the converter is negative. 1. The direction indicator plug of the sensor is opposite to the flow direction of the fluid. 2. There is a reverse connection between X and Y or A and B in the junction box of the sensor. The converter outputs an excess range. 1. The flow measurement range value is less than the actual measurement value. 2. The fluid is not full of the pipe. 3. The excitation coil is open. The output signal fluctuates too much. 1. There is gas at the sensor electrode, which causes poor contact between the electrode and the medium. 2. There is sediment on the electrode. The output signal gradually drifts to zero. 1. Water enters the sensor and 2 electrodes are covered. Under standard conditions, the periodic cleaning cycle depends on the scaling rate, and the electrodes and measuring heads (measuring tubes) are cleaned.

·Immersion sealing, can work in wet or underwater;·The radio frequency card technology is adopted, which is convenient for users to operate;·Pilot valve, free from scale and water pressure, more safe and reliable·Generally, IC card water meter adopts ball valve, and valve opening and closing are easily affected by scale and water pressure. The ball valve ball and the outer wall will produce scale when they are immersed in water for a long time, which will increase the friction resistance, thus affecting the on-off valve; When the water pressure increases, the resistance of the ball valve will also increase exponentially, which will have a great impact on the opening and closing of the valve;·The cork type working principle of the pilot valve is not affected by scale and water pressure;·The pilot operated electric control valve with magnetic and hydraulic combination technology has low power consumption, and the valve can be opened and closed reliably and stably under low pressure.·The base meter and valve adopt magnetic drive and special isolation seal design to solve the problem of dynamic seal and water leakage of ordinary IC card water meter.·The ball of the ball valve is directly connected with the motor, and is generally sealed with a rubber ring. Over time, it is easy to age and deform, resulting in water leakage; The base meter and valve of Longkang IC card water meter adopt magnetic drive, and the isolation layer is reinforced and sealed with copper shell. The maximum pressure resistance can reach 35kg, and there will be no water leakage;·Anti magnetic: When a magnetic object is close to the water meter, the water meter will automatically close the valve to prevent the magnetic object from interfering with the water meter metering;
