The advantages and technical indicators of integrated vortex flow meter
Temperature and pressure compensation integrated vortex flowmeter performance advantages:
1. The advantage is that the vibration resistance is particularly good, no zero drift, high reliability.
2. The universality of the temperature and pressure compensation integrated vortex flowmeter sensor is very strong, so that the sensor has good interchangeability. Advanced CNC equipment is used to process the surface body and vortex generator of the sensor, etc., to ensure the processing accuracy, so that the universality of the parts (especially the vortex generator) is strong, so that the repeatability and accuracy of the sensor will not be affected by the replacement of the parts; It can produce a strong and stable vortex signal.
3. Within a certain range of Reynolds number, the flow characteristics are not affected by fluid pressure, temperature, viscosity, density, and composition, but are only related to the shape and size of the vortex-generating body.
4. Output pulse signal or analog signal proportional to the flow, no zero drift, high precision, convenient and computer networking.
5. Simple and firm structure, no moving parts, high reliability, easy to use and maintain.
6. The detection element is not in contact with the medium, stable performance, long service life, the sensor uses the detection probe and the vortex generator body installed separately, and the high-temperature piezoelectric crystal is sealed in the detection probe, not in contact with the measured medium, so the vortex flowmeter has the characteristics of simple structure, good versatility and high stability.
7. Wide measuring range, range ratio up to 1:10.
8. There is no need to compensate when measuring the volume flow, and the output signal of the vortex is actually linear with the flow rate, that is, proportional to the volume flow. The purpose of pressure and temperature compensation is to obtain the density of the fluid, multiplied by the volume flow rate to obtain the mass flow rate, if the volume flow of the gas is measured, there is no need to compensate.
