　　2、 Structural form:

　　1. Sensor:

　　The sensor mainly consists of a measuring conduit, measuring electrodes, excitation coils, iron cores, magnetic yokes, and a housing.

　　a、 Measurement catheter: composed of stainless steel catheter, lining, and connecting flange, it is a carrier for measuring the on-site working conditions of the measured liquid.

　　b、 Measurement electrode: a pair of electrodes installed on the inner wall of the measurement catheter, perpendicular to the axial flow direction, to generate signals for the measured liquid.

　　c、 Excitation coil: The upper and lower excitation coils that generate a magnetic field inside the measuring conduit.

　　d、 Iron core and magnetic yoke: Introduce the magnetic field generated by the excitation coil into the liquid and form a magnetic circuit.

　　e、 Shell: Instrument outer packaging.

　　2. Converter: It is an intelligent secondary meter that amplifies and processes flow signals. After being operated by a microcontroller, it can display flow and cumulative measurement, and output signals such as pulses and analog currents for measuring or controlling fluid flow.

　　3. Product assembly form: It is divided into two forms: integrated and split.

　　a、 Integrated: The sensor and converter are installed together.

　　b、 Split type: Sensors and converters are installed separately, forming a flow metering system through connecting cables.

　　c、 To meet the requirements of measuring different media, there are multiple choices for the lining and electrode materials of sensors.

　　3、 Main technical data:

　　Power supply: 85V-250VAC/16V-36VDC;

　　Instrument display: High definition backlit LCD display (126 x 48 dot matrix), which can simultaneously display instantaneous, cumulative flow and other information and related units, with Chinese/English menu support;

　　Communication interface: It has digital communication signal outputs such as RS485, RS232, Hart, and Modbus;

　　Anti interference: Built in comprehensive anti-interference multi-level protection circuit with full digital processing, significant anti-interference performance, effectively eliminating on-site vibration and power frequency interference;

　　Data storage: With comprehensive data backup and recovery functions, on-site maintenance free;

　　Excitation method: Three types of excitation frequencies are standard, 1/10, 1/16, and 1/25 power frequency (1/4, 1/8, and 1/32 are optional), to meet more measurement needs;

　　Operation method: It has two functions: key operation and magnetic key operation. The operation is simple and fast, easy to learn and understand.
