Product Overview

Stress type vortex flowmeter is a type of velocity flowmeter, which is based on the Karman vortex theory and uses piezoelectric crystal inspectionMeasure the vortex frequency generated by the vortex generator in the pipeline to determine the flow rate of the fluid. This series of vortex flowmeter is a carefully designed product based on the comprehensive absorption of advanced technology from developed countries and the summary of years of research and production experience. It achieves product intelligence, standardization, serialization, universality, production mold, and ensures the reliability of product quality. It has the characteristics of advanced circuit, low power consumption, wide range ratio, simple structure, low resistance loss, sturdy and durable, wide application, long service life, stable operation, and easy installation and debugging. Widely used in industries such as petroleum, chemical, power, light industry, and power heating, it can also be used for flow measurement of fluid pipelines in urban water supply and medical industries.

Features:

1 No movable parts, long-term stability, simple structure for easy installation and maintenance.

2. The sensor output is a pulse signal, whose frequency is linear with the actual flow rate of the measured fluid, and there is no zero drift,The performance is very stable, and the structural forms are diverse, including pipeline and plug-in flow sensors.

3High precision, usually the measurement accuracy of liquids is ±1%The measurement accuracy of gas is±[A1]1.5%.

4. The measurement range is wide, with a Reynolds number of2×104~7×106 Within the range, accessible1:20.

5. Small pressure loss (approximately equivalent to that of an orifice flowmeter)1/4~1/2）It belongs to energy-saving flow meters.

6. The installation method is flexible, and it can be installed horizontally, vertically, and at different angles according to the different process pipelines on site.

7. Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance.

8. Using ultra-low power microprocessor technology,1 section3.6V10AHLithium batteries can be used3Years or more.

9. Correction of instrument coefficient nonlinearity by software to improve measurement accuracy.

10. Low pressure loss and wide range of measurement.

11. AdoptingEEPROMPower off protection for accumulated traffic, with a protection time greater than10 year
