Selecting points and linking methods of measuring and controlling instruments

Vortex flowmeter is based integrated absorption of advanced technology from developed countries and summarizes years of research production experience on elaborate production, the production of intelligent, standardization and universalization, mold production, ensure the appearance of the product quality.

The measuring and controlling instrument has the advantages of advanced circuit, low power consumption, wide measuring range, simple structure, small resistance loss, strong and durable, wide use, long service life, stable work, easy installation and debugging, etc..

1., according to the sensor connection way is divided into flange type and clip type.

2., according to the way are divided into thermal, stress, capacitive, strain, ultrasonic, vibration, photoelectric and fiber type.

3., according to the use of divided into ordinary type, explosion-proof type, high temperature type, corrosion-resistant type, low temperature type, plug-in and automotive special type.

4., according to the sensor and converter components, divided into one type and separate type.

5. according to the principle of measurement is divided into volume flow meter, mass flowmeter.

Matters needing attention

What should I pay attention to when choosing a vortex flowmeter? Now let's give you two tips on this topic:

The quality of the measuring and controlling instrument is related to two parts: probe and circuit board.

1. vortex flowmeter probe: there are two pieces of piezoelectric crystal, one for anti vibration interference, one for detection. The probe leads are two lead wires of the detecting piece, the probe shell is inserted by the vortex tube wall, and is fixed on the wall of the vortex tube through a fixed flange. If the temperature is higher, it will damage the sealing porcelain, so that the performance of the probe will decline, and even damage the probe.

2. vortex flowmeter circuit board: steam vortex flowmeter design is directly related to the vortex generated by the signal is correct or not, we can usually oscilloscope to see the flow of the flowmeter generated at work.
