Description of DN65 electromagnetic flowmeter

Description :

　　This product is a volumetric flow measurement instrument that is not affected by the temperature, viscosity, density, or conductivity (within a certain range) of the measured medium during the measurement process. Therefore, after being calibrated with water, the flowmeter can be used to measure the flow rate of other conductive liquids.

　　1、 Category:

　　The FH-1000 series electromagnetic flowmeter consists of a sensor and an intelligent signal converter. According to the assembly form of the converter and sensor, it can be divided into two structures: integrated and split.

　　Integrated: The converter and sensor are directly assembled as a whole and cannot be separated. Commonly used in sites with good environmental conditions.

　　Split type: The converter is composed of a dedicated cable and a sensor to form a product, with the sensor installed on site and the converter installed in a location with better conditions. Commonly used in sites with poor environmental conditions, such as underground wells, high temperatures, and places that are difficult for personnel to reach.

　　2、 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

　　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.
