1. Why does the smart flowmeter display a negative value of 23.85 during operation?

Xuner Instrument answers for you: The reason for the negative flow value is:

1. The sensor was not installed according to the flow direction label, causing the measurement direction to be opposite. Solution: Reinstall. Excellent

2. Reverse the sensor signal line, as the intelligent electromagnetic flowmeter has forward and reverse flow measurement functions, it displays reverse flow. Solution: Swap the signal line.

3、 Measure whether the pipeline is empty or not filled with gas. At this point, the flow meter will display negative numbers or fluctuating flow values. Solution: Fill the pipeline with the measured medium to enable the flowmeter to have measurement conditions. For detailed information, please refer to flow-meter.com.cn

Tianjin Xuner, electromagnetic flowmeter is cheaper, divided into intelligent electromagnetic flowmeter and plug-in electromagnetic flowmeter.. Intelligent electromagnetic flowmeter [applicable medium] Any conductive liquid [not applicable medium] Non conductive liquid, gas, steam negative pressure pipeline cannot be used [LDS product features] 1) Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. 2) There are no flow blocking components inside the measuring tube, no pressure loss, and low requirements for straight pipe sections. Has unique adaptability to slurry measurement. 3) Reasonably selecting electrode and lining materials, which h

ave good corrosion resistance and wear resistance. 4) Full digital quantity, strong anti-interference ability, reliable measurement, high accuracy, flow measurement range up to 150:1. 5) Ultra low EMI switching power supply, suitable for a wide range of power supply voltage changes, with good EMI resistance performance. 6) Adopting a 16 bit embedded microprocessor, it has fast computing speed, high accuracy, programmable low-frequency rectangular wave magnetization, improved stability of flow measurement, and low power consumption. 7) Using SMD devices and surface mount technology, the circuit has high reliability. 8) There are no movable parts or flow blocking components inside the pipeline, and there is almost no additional pressure loss during measurement. 9) On site, the range can be modified online according to the actual needs of the user. 10) The measurement results are independent of physical parameters such as flow velocity distribution, fluid pressure, temperature, density, viscosity, etc. 11) High definition Chu Du backlit LCD display, fully Chinese menu operation, easy to use, simple to operate, easy to learn and understand. 12) Equipped with RS485

5, RS232

2, Hart and Modbus Profibus DP digital communication signal outputs (optional). 13) It has self checking and self diagnosis functions. 14) The hourly total recording function records the total flow rate in hours, suitable for time-sharing metering system (optional). 15) There are three internal integrators that can display the forward cumulative amount, reverse cumulative amount, and difference cumulative amount respectively. The internal power down clock can record 16 power down times (optional). 17) Infrared handheld operator, 115KHZ communic
