DN300 large pipeline electromagnetic flowmeter

Description :

　　DN300 large pipeline electromagnetic flowmeter

　　The main components of this product are: measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. It is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Including highly corrosive liquids such as acids, alkalis, salts, etc.

　　1、 Characteristics:

　　The 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 forms: integrated and separated.

　　High definition LCD backlit display.

　　3、 Selection:

　　The selection of instruments is a very important task in instrument applications. According to relevant data, 2/3 of instrument failures in practical applications are caused by incorrect selection and installation of instruments, and special attention should be paid.

　　collect data

　　① Name of the tested fluid;

　　② Flow range;

　　③ Work pressure;

　　④ Working temperature.

　　The tested fluid must have a certain conductivity, with a conductivity of ≥ 5uS/cm.

　　Traffic and minimum traffic.

　　The actual working pressure must be less than the rated working pressure of the flowmeter.

　　The working temperature must meet the temperature requirements specified by the flowmeter.

　　Determine if there is negative pressure present.
