Flow meter

  Phenomenon Reason Treatment Measures Instantaneous flow rate with constant maximum value 1. The cable wire is disconnected or the sensor is damaged. 1. Replace the cable or replace the sensor. 2. The fuse in the transmitter is burnt out 2. Replace the fuse. 3. Sensor measuring tube blockage 3. After unblocking, tap the sensor […]

  Phenomenon Reason Treatment Measures No display when fluid is flowing normally 1. Power cord, fuse, etc. have a break or poor contact. 1. Use an ohm meter to troubleshoot. 2. Poor contact inside the display. 2. Use the replacement “spare version” method to check. 3. The coil has broken wires. 3. Check the coil

  Phenomenon Reason Treatment Measures Float flowmeter pointer jitter 1. Medium pulsation. 1. Increase the damping. 2. Unstable air pressure. 2. Using voltage or current stabilization device. The pointer stops at a certain position and does not move 1. Open the valve too fast and the float is stuck. 1. Slow down the opening speed

  Phenomenon Reason Treatment Measures The rotor does not turn 1. Filter clogged. 1. Clean the filter. 2. Impurities enter the flowmeter to make the rotor stuck. 2. Check the filter for damage and clean the inside of the flowmeter. The rotor rotates normally but the counter does not count 1. Poor engagement of the

1. The transmitter is made of Cast Aluminum, the sensor guide pipe is made of stainless steel, and the flange and body surface are made of carbon steel. 2. Pressure can do national standards and also can do the America Standard, and Generally, 150 # and 300 # are most frequently made.  3. Transmitter protection level

1. Different working principles Electromagnetic Flowmeter Working Theory The electromagnetic flowmeter is a flowmeter that performs flow measurements according to Faraday’s law of electromagnetic induction. The advantage of the electromagnetic flowmeter is that the pressure loss is extremely small and the measurable flow range is large. The ratio of the maximum flow rate to the

Rotor flowmeter used in small pipe diameter and low flow rate. Commonly used instrument caliber 40-50mm below, the smallest caliber to 1.5-4mm. suitable for measuring low flow rate small flow rate and liquid. For example, caliber 10mm below the nominal pipe diameter of the full flow of glass tube rotor flowmeter, flow rate only in

1. For the selection of remote transmission out type metal tube float rotor flowmeter, to choose suitable for the use of premises explosion-proof type requirements of the rotor flowmeter; installation should also pay attention to the instrument after the energization of the shell fastening and sealing of the junction, has reached the explosion-proof, protection, anti-erosion

In order for the rotameter to work properly and to achieve a certain level of measurement accuracy, the following points should be noted when installing the flowmeter. 1. The rotameter must be installed vertically in the vibration-free pipeline. Fluid flow from the bottom up through the flowmeter, and the vertical degree is better than 2

Relying on the advantages of small pressure loss and large detection range, it has become a very common flow measurement instrument in industrial control, which is not only easy to use but also has the advantage of strong compatibility. Especially suitable for low flow rate and small flow rate of the medium flow measurement. Rotor
