Description of DN20 Electromagnetic Flow Meter

Description :

　　This product has measurement value power-off protection and air traffic control alarm function. The flow direction of the fluid can be set, so the installation of the sensor is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.

　　1、 Technical parameters:

　　Caliber: DN10-DN2000 (mm) Special customizable

　　Nominal pressure: 0.6-4.0MPa (differentiated by caliber, special high pressure can be customized)

　　Electrode materials: 316L stainless steel, Hastelloy C, Hastelloy B, titanium, tantalum, platinum iridium electrode

　　Lining materials: polytetrafluoroethylene (PTFE), perfluoroethylene propylene (FEP), chloroprene rubber (Ne), polyurethane rubber (PU)

　　Medium temperature: -40~180 ℃ (limited by the temperature resistance characteristics of the lining material, as follows:

　　Neoprene rubber lining: -40~+80 ℃ Polyurethane rubber lining: -10~+60 ℃

　　PTFE lining: -30~+120 ℃, PTFE lining: -30~+180 ℃

　　Shell material carbon steel (customizable stainless steel shell)

　　Protection levels IP65, IP67, IP68

　　Working power supply 220VAC, 24VDC

　　Current output 4~20mA

　　2、 Performance characteristics:

　　The instrument structure is simple, reliable, without moving parts, and has a long working life.

　　No flow blocking components, no pressure loss or fluid blockage.

　　No mechanical inertia, fast response, good stability, can be applied to automatic detection, adjustment, and program control systems.

　　The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc.

　　Different combinations of PTFE or rubber lining materials and electrode materials such as Hc, Hb, 316L, Ti can adapt to the needs of different media.

　　There are various flow meter models available, including pipeline type and plug-in type.

　　Using EEPROM memory, the storage of measurement and operation data ensures safety and reliability.

　　It has two types: integrated and separated.

　　3、 Selection of installation location:

　　1. The flow direction indicator on the sensor and the direction of the measured medium flow inside the pipeline must be *.

　　2. The installation position must ensure that the measuring tube is filled with the measured medium.

　　3. Choose a location with smaller fluid flow impulse, which should be away from the pump and local resistance components (valves, elbows, etc.)

　　4. When measuring two-phase fluids, a location that is not prone to phase separation should be selected.

　　5. Installation in areas with negative pressure inside the pipe should be avoided as much as possible.

　　6. When the measured medium easily causes adhesion and scaling on the inner wall of the electrode and measuring tube, it is recommended that the flow velocity inside the measuring tube should not be less than 2m/s.
