Product features

The characteristics of pipeline vortex flowmeter are small pressure loss, large range and high precision. It is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time. This vortex flowmeter has analog standard signal and digital pulse signal output, which is easy to use with digital systems such as computers. It is an advanced and ideal measuring instrument

Product features:

 

1. Large and clear LCD: clear and fast data display, ensuring fast data reading

2. Integrated meter head: 20 years of professional meter head manufacturer, SMT surface mount technology is used internally, and the assembly density is high

3. Imported high-quality circuit board is adopted, with strong anti-interference, ensuring measurement accuracy and durability

4. The high-precision probe adopts 304 stainless steel inner sealed piezoelectric chip to form a vortex sensor, and the signal is stable

5. Equipped with 3.6V high concentrated energy lithium battery, with high storage energy density and service life of more than 2 years
