4. Programmable low frequency square wave field excitation, improving measurement stability and reducing power consumption.
5. Implementing 16 bits MCU, providing high integration and accuracy; Full-digital processing, high noise resistance and reliable measurement; Flow measurement range up to 1500:1.
6. High definition LCD display with backlight.
7. RS485 or RS232 interface supports digital communication.
8. Intelligent empty pipe detection and electrodes resistance measurement diagnosing empty pipe and electrodes contamination accurately.
9. SMD component and surface mount technology (SMT) are implemented to improve the reliability.

Main Applications

TQMF electromagnetic flowmeter can be used to measure the volume flow of conductive fluid in a closed pipeline. It is widely applied in the flow measurement and control in the fields of chemical and petroleum industry, metallurgy industry, water and waste water, agriculture and irrigation, paper making, food and beverage industry and pharmaceutical industry. 1.3Ambient Conditions Ambient temperature: sensor: -25℃ to + 60℃; converter: -25℃ to + 60℃. Relative humidity: 5% to 90%; 1.4Working Conditions Maximum fluid temperature: Compact type: 60℃ Remote type: Teflon 150℃ Neoprene 80℃; 120℃ Polyurethane 70℃ Fluid conductivity: ≥ 5S/cm

Measuring Principles

The measuring principle of electromagnetic flowmeter is based on the electromagnetic induction law of Farady. The sensor is mainly composed of measuring tube with isolate lining, a pair of electrodes installed by penetration of the measuring tube wall, a pair of coils and iron core to produce working magnetic field. When the conductive fluid flows through the measuring tube of the sensor, the voltage signal in direct proportion to the average flow velocity of the fluid will be inducted on the electrodes. The signal is amplified and treated by the transmitter to realize various display functions.

Converter Circuit Schematic

The converters supplies a stable exciting current to the coil in the sensor of electronetic flowmeters to get B constant and amplifies the electromotive force and convert it into standard signals of current or frequency so that the signals can be used for displaying, controlling and processing. The schematic of converter circuit is shown in Fig. 2.1.
