Flow meter

1. No output display on the transmitter Initial inspection and testing Solutions Check that the power supply is not connected backward Connect the correct polarity to the power supply Measuring the power supply to the transmitter for 24 V DC voltage It must be ensured that the supply voltage to the transmitter is ≥ 12 […]

In the petrochemical, chemical, electric power, metallurgy, municipal, pharmaceutical and other industries, the technical difficulty and complexity of flow measurement are quite high, the study of flow measurement to improve product quality, reduce the operating costs of enterprises, address energy saving and environmental protection play an important role. The electromagnetic flowmeter has no resistance, and

Ambient:Temperature: -10°C to +55°CPressure: 86 to 106 KPaRelative Humidity: 5% to 90% Power Supply:Sensor: +12V DC (Optional: +24V DC)Transmitter: +24V DCField Display Type B: Integral 3.2V Lithium Battery (Others available on request)Field Display Type C: +24V DC Fluid Temperature and Pressure:Temperature: -20°C to +110°CPressure: Fluid pres should be limited according to rating.

Liquid turbine flowmeter has these components: turbine, spiral-shaped vane, bearing of turbine, and preamplifier. A liquid turbine flowmeter is a relatively popular flowmeter, the device has its own characteristics, specifically in the fully intelligent, digital circuit design, simple structure, lightweight, less processing parts, easy maintenance, responsive, large flow capacity and can adapt to high parameters.

  Phenomenon Reason Treatment Measures The pipeline has a flow， meter without an output 1. The power supply is malfunctioning. 1. Repower or replace the power supply. 2. The power supply is not connected. 2. Turn on the power. 3. The connection cable is broken or the boundary line is wrong. 3. Rewire and check

Phenomenon Reason Treatment Measures Indicates zero or very small movement 1. The balance valve is not fully closed or leaking. 1. Close the balance valve and repair or replace it with a new one. 2. The high and low-pressure valve at the root of the throttling device is not open. 2. Open the high and
