Product Parameters

Sichuan VACORDA Instruments Manufacturing Co., Ltd.is a professional production-manufacturing enterprise specialized in designing, producing and marketing of instruments and apparatuses. Our company has been established for 23 years since 1997 to grow up to be a team of high-quality, united, hard-working and truth-seeking characters. Solid foundation has been established.

In 2017, we moved into our new factory whhich occupies the area about 20000 square meter, the workshop of 6900 square meter, R&D department of 1180 square meter, integrated office building of 1260 square meter, and we have established the high accuracy flow calibration lines.

Precautions

(1) Before installing the turbine flow meter, clean the piping. When the measured media is unclean, add a filter. Otherwise, the turbine and bearing are easily stuck and no flow can be measured.

(2) When disassembling the flowmeter, the magnetic induction part cannot be collided.

(3) Set the meter factor before commissioning. Carefully check to make sure that the instrument wiring is correct and the grounding is good before sending power.

(4) When installing the turbine flowmeter, the front and rear duct flanges should be horizontal, otherwise the pipeline stress has a great influence on the flowmeter.

Test steps
(1) In the case where the pipe is filled with medium, use a multimeter to measure the resistance between terminals A, B and C. The resistance between A-C and B-C should be equal. If the difference is more than 1 time, there may be leakage of the electrode, condensation on the outer wall of the measuring tube or inside the junction box.
(2) Under the condition of lining drying, the insulation resistance between A-C and B-C (should be greater than 200 MΩ) is measured by MΩ meter. Then use a multimeter to measure the resistance of the two electrodes in terminals A and B and the measuring tube (should be in short-circuit communication). If the insulation resistance is small, indicating that the electrode is leaking, the entire flowmeter should be returned to the factory for repair. If the insulation is reduced but there is still more than 50 MΩ and the inspection result of step (1) is normal, it may be that the outer wall of the measuring tube is damp, and the inside of the outer casing can be dried by a hot air blower.
(3) Use a multimeter to measure the resistance between X and Y. If it exceeds 200 Ω, the excitation coil and its lead wire may open or contact poorly. Remove the terminal block check.
(4) Check the insulation resistance between X, Y and C, which should be above 200 MΩ. If it is lowered, use hot air to dry the inside of the casing. In actual operation, the decrease in the insulation of the coil causes the measurement error to increase and the signal output from the meter to be unstable.
(5) If it is determined that the sensor is faulty, please contact the manufacturer of the electromagnetic flowmeter. The general site cannot be solved and needs to be repaired by the manufacturer.
