ZXLDG series electromagnetic flowmeter
On the top of the board, there are two
The sea is on say distribution, fluid pressure, temperature, density and viscosity.
The site can be modified according to the actual needs of the user.
High definition backlight LCD display, full Chinese menu operation, easy to use, easy to understand and easy to understand.
SMD devices and surface mounted (SMT circuit reliability is high).
The 16 - bit embedded microprocessors are used in the system, and the calculation speed is fast, the precision is high, and the frequency of the low frequency rectangular wave excitation
is improved
The stability of flow measurement and low power consumption.
Full digital processing, strong anti-interference ability, reliable measurement, high precision and flow measurement range can reach 150:1
Ultra low EMI switching power supply, the use of power voltage varies widely, anti-emc is good
Within the inside of the device, three integrators can show the positive cumulative volume and the difference volume, and the internal clock can be recorded
16 times of power loss
It has the output of digital communication signals such as RS485, RS232, Hart and Modbus.
The system has self-examination and self-examination function
1 overview
The working principle of
The principle of electrical flowmeter is based on Faraday electromagnetic induction law. A flowmeter measuring tube is an inner liner
Non-conductive alloy short tube of edge material. The two electrodes are perforated along the diameter of the pipe and the wall is fixed to the measuring tube. The electricity
The polar head is basically flush with the inner surface of the lining. The excitation coil is excited by the wave pulse of the two sides, and will be in the measurement tube axis
A magnetic flux density is generated in a vertical direction.
At this point, if there is a certain conductivity
The fluid flows through the measuring tube. The cutting magnetic forc
