Specifications
1)    Programmable low-frequency rectangular wave excitation: 1/8, 1/*6,  1/*2 of standard power frequency
2)    Excitation current: **0~**0mA, supports various types of sensors of different manufacturers
3)    Measurable flowrate range: 0.1~*5m/S, high stability and  Reading stability is up to 0.**1m/S ; range ratio: **0:1
4)    Bi-directional measurement with three totalizers: Forward total, Reverse total and Difference total. 
5)    Measurement range can be switched in order to effectively improve the accuracy of analogue current and frequency output, this function is especially useful for the scenario that flowrate changes significantly between daytime and night and therefore range adjustment is necessary.
6)    Build-in anti-interference protective circuit, efficiently eliminate field interference and power frequency interference; Reliable measurement with full-digital processing,
7)    Converter adopts surface mount technology (SMT), and has self-test and self-diagnosis functions.
8)    Ultra-low EMI switching power, compatible to large range of power voltage, low temperature drift, good EMC performance
9)    Intelligent data acquisition and processing, Supportive of non-linear multi-point sensor modification to improve accuracy. Support empty pipe and electrodes inspection.
*0)    Default RS**5 digital communication interface with MODBUS protocol. PROFIBUS and HART protocol for option.
