　　LDG electromagnetic flowmeter manufacturer direct sales

　　1. Overview:

　　This product can measure the flow rate of dirty media, corrosive media, and suspended liquid-solid two-phase flow. This is because there are no flow obstructing components inside the instrument measuring tube, and only the inner lining and electrodes of the measuring tube are in contact with the measured fluid. The material can be selected according to the properties of the measured fluid. For example, using polytetrafluoroethylene or polytetrafluoroethylene as lining can measure various corrosive media such as acids, alkalis, salts, etc; The use of wear-resistant rubber as an inner lining is particularly suitable for measuring liquid-solid two-phase flows such as slurry and cement slurry with solid particles and high wear, as well as various suspended liquids such as fibrous liquids and pulp.

　　2、 Characteristics:

　　1. There are no movable parts inside the measuring tube, and the sensor has a long service life.

　　2. There are no resistance components inside the tube, so there is no additional pressure loss, no blockage, and reliable measurement.

　　3. Strong anti-interference ability, small size, light weight, easy installation, low maintenance, and wide measurement range.

　　4. Measurement is not affected by changes in fluid temperature, density, pressure, viscosity, conductivity, etc.

　　5. It can be cut, modified and installed on old pipelines, with simple construction and small engineering quantity.

　　6. Compared with general flow meters, it has low cost and installation expenses, making it particularly suitable for measuring flow in large and medium-sized pipelines.

　　7. The sensing voltage signal of the sensor is linearly related to the average flow rate, therefore the measurement accuracy is high.

　　8. Chinese LCD display, displaying cumulative flow, instantaneous flow, flow rate, flow percentage, etc.

　　4、 Installation:

　　⑴ 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.

　　⑵ 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.

　　⑶ 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%.

　　⑷ Choose a place that is easy to maintain and has convenient activities.

　　The flowmeter should be installed at the rear end of the water pump and must not be installed on the suction side; The valve should be installed on the downstream side of the flow.
