Standard signal generator for electromagnetic flowmeter

Electromagnetic flowmeter signal generator is a high-precision test tool designed to calibrate the converter.
1. Working condition
    Ambient temperature: 0～+40°C;
    Relative humidity: 5%～85%;
    Power supply: 9VDC;
    Working current: < 30mA.

Features

2. This product is portable.
3. The standard signal generator converts the low-frequency square wave exciation current of the electroamgnetic flowmeter into pulsed voltage by high-precision resistor. The pulsed voltage is then divided into micro-voltage signal to simulate the flow signal, which is input to the MBmag converter to check its linearity and other performance.
4. The standard signal generator can simulate bi-directional flow signals to test the flow direction detection of the MBmag converter.
