Tianjin Haisu Instrument Co., Ltd. has a high-quality, high-level technology development team and an effective management team. It is committed to providing customers with safe, durable and accurate automated industrial instruments. The products have won praise and trust at home and abroad . Combining more than ten years of flowmeter production experience and feedback from numerous customers, the breakdowns and solutions that occur during the use of turbine flowmeters are summarized below.

1, mounted on the turbine flow meter is not suitable where strong vibration is applied by the widely known, but in the case of frequent changes in the magnetic field, the vortex flow sensors may measure the output signal higher than normal. Practice has proved that in the field without gas flow, when the vortex flow sensor is in the changing magnetic field, the turbine flowmeter sensor will induce an error signal to output when the magnetic field changes, and when the change is over, the instrument is in a stable magnetic field. The meter will output a normal signal.

2, coke oven gas temperature is high because the factory, high humidity, and therefore there is moisture present in the gas delivery. The flow of gas drives the water to reciprocate and fluctuate, creating a pulsating flow. When the vortex flow sensor is in this fluid state, the output data suddenly changes, and it cannot reflect the production status at all.

3 , due to more impurities in coke oven gas, easy to crystallize, impurities condensed in the sensor head, resulting in measurement inaccurate. As the temperature rises, the impurities volatilize, the sensitivity increases, and the signal increases; on the contrary, it decreases. As a result, data is unstable.

4, the instrument does not meet specifications ground line, so that the strong electric 50Hz interference entering a normal signal when the output signal is higher than a normal 50Hz, otherwise it will output an error signal.

5 , the instrument line during the wiring is not true, resulting in the transmission of signals in the intermittent.

Turbine flowmeter fault solution is as follows:

1, the installation instrument, the connection process, to ensure the accuracy of each link, which comprises a front mounting site investigation aspects, the installation process instrumentation wiring system grounding lines, thereby ensuring the real data is detected and can be output accurately .

2, for the operation of the metering system can be used "double ghost metering control, contrast confirmation" method, and "substitution" for trouble-free operation of the measuring instrument and confirmed negative.

3, strengthen the management of turbine flowmeter system data, set the timer print function, the operation of the instrument for analysis combined with production conditions in accordance with the print data.

4, drainage pipes regularly, in particular the straight pipe section before the water is provided according to specific circumstances hand periodically discharged, reducing the moisture in the metering pipe as possible, the maximum negative pulsating fluid.

5 , The instrument is cleaned on a regular basis. If necessary, the sensor head of the instrument can be purged to avoid the condensation of impurities at the sensor head. In the cold season, the addition of heat tracing devices in the straight section of the metering section and the meter section also helps to reduce the condensation of impurities at the meter.
