First, the vortex flowmeter amplifier works vortex flowmeter amplifier is the actual user in the field can use only part of debugging. The role of the amplifier is the vortex signal generated by the fluid flow in the pipeline, amplified by the circuit, after shaping filter output square wave signal. When the fluid in the tube through vortex flow sensors, piezoelectric crystal element produces an alternating electrical charge through the charge amplifier converts the charge amount proportional to the alternating voltage signal, and then sent to the voltage amplifier, the voltage amplifier has a test point TP1, voltage amplification can be adjusted by potentiometer W1. Low-pass filter is used to remove high-frequency noise signal intelligent vortex flowmeters offer, let vortex frequency signal by the sensor measurement range, the filter output is a test point TP2. Schmitt trigger sine wave signal into a square wave signal, the output amplifier Intelligent Vortex flowmeter test points after the trigger for TP3. Static checking vortex flowmeter amplifier at the scene of an amplifier with a multimeter to check the static level, as follows: 1. 50V DC multimeter file, check the input supply voltage is about + 24V intelligent vortex flowmeter, if through the barrier Intelligent Vortex flowmeter retail, then is about 18V. 2. Use a multimeter DC 50V files, check the operational amplifier (LM324, or TL064, TL084), 4 feet for the power supply voltage (approximately + 24V), 1,7,14 foot should be 1/2 the power supply voltage. 3. Check with a multimeter DC 50V-speed dual operational amplifier (LM358, or TL062, TL082), 8 feet for the power supply voltage (approximately + 24V), 1,5 feet should be 1/2 the power supply voltage. Installation site with dynamic signal oscilloscope oscilloscope can be used to check the sensor amplifier is working properly. TP2 oscilloscope measurements with AC0.5V file, the peak signal amplitude 0.7V.
