Description of Domestic Electromagnetic Flowmeters

Description :

　　This product has a simple and reliable structure, no movable parts, and a long working life. No flow blocking components, no pressure loss or fluid blockage.

　　1、 Characteristics:

　　The measurement of flow rate is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy (0.3-0.5%).

　　There is no obstruction in the measuring pipeline, so there is no additional pressure loss, which has significant energy-saving significance.

　　There are no movable parts inside the measuring pipeline, so the sensor has a long lifespan.

　　The straight pipe section required for the sensor is relatively short, making it easy to install.

　　Reasonable selection of electrode and lining materials can resist corrosion and wear.

　　2、 Technical parameters:

　　Nominal diameter (mm) (special specifications can be customized)

　　Pipeline type PTFE lining: DN10~DN600

　　Pipeline rubber lining: DN40~DN2200

　　Flow direction: positive, negative, net flow

　　Range ratio: 150:1

　　Repetitive error: ± 0.1% of the measured value

　　Accuracy level: Pipeline type: 0.5 level, 1.0 level

　　PTFE lining: -30 to+100 ℃; High temperature PTFE lining: -20 to+180 ℃

　　Rated working pressure: (high pressure can be customized) DN10- DN150: ≤ 1.6MPa; DN200－DN350：≤1.0MPa

　　DN400－DN1000：≤0.6MPa； DN450－DN2200：≤0.25MPa

　　Flow velocity range: 0.1-15m/s

　　Conductivity range: The conductivity of the measured fluid is ≥ 5 μ s/cm

　　3、 Installation:

　　1. Try to avoid ferromagnetic objects, high radio frequency, strong vibration interference sources, and equipment with strong electromagnetic fields (such as high-power motors, large transformers, etc.) to avoid magnetic fields affecting the working magnetic field and flow signal of the sensor.

　　2. It should be installed in a dry and ventilated place as much as possible, and should not be installed in damp or water prone areas.

　　3. It is advisable to avoid direct sunlight and rain as much as possible, and the ambient temperature should be between -20 and 60 ℃ with a relative humidity of less than 95%.

　　4. Choose a place that is easy to maintain and has convenient activities.

　　5. The flowmeter should be installed at the rear end of the water pump and must not be installed on the suction side.
