1. SUMMARY
Features:
l Measurement is not affected by the variation of flow density, viscosity, temperature, pressure and conductivity. High accuracy measurement is guaranteed according to the linear measurement principle.
l No obstacle in the pipe, lower pressure-loss and lower requirement for straight pipeline.
l DN 6 to DN2000 covers a wide range of pipe size. A variety of liners and electrodes are available to satisfy different flow characteristic.
l Programmable low frequency square wave field excitation, improving measurement stability and reducing power consumption.
l 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.
l High definition LCD display with backlight.
l RS485 or RS232 interface supports digital communication.
l Intelligent empty pipe detection and electrodes resistance measurement diagnosing empty pipe and electrodes contamination accurately.
l SMD component and surface mount technology (SMT) are implemented to improve the reliability.
