Vortex Flowmeter

LUGB series vortex flowmeter can be used for flow detection and measurement of various gases, liquids and steam.
LUGB series vortex flowmeter can be used with the intelligent flow totalizer produced by our company, and can also be used with the intelligent instruments produced by other instrument manufacturers, with the characteristics of strong versatility.

Detail

Principle and structure

LUGB series vortex flowmeter is a flow meter that uses piezoelectric crystal as a detection element and outputs a standard signal proportional to the flow rate. The meter can be directly matched with the DDZ-Ⅲ instrument system, or it can be used with a computer and a distributed control system to measure the flow parameters of different media. The meter is based on the detection principle of fluid vortex street. The piezoelectric crystal for detecting vortex street does not contact the medium. The meter has the characteristics of simple structure, good versatility and high stability.

Product Features

1. High temperature resistance: The sensor measuring probe is encapsulated with a special process, and the high temperature resistance can reach 350℃

2. Strong versatility: Strong versatility, can measure unclean gases and liquids

3. Long service life: The sensitive element is sealed in the probe body, the detection element does not contact the measurement medium, and the service life is long

4. Compensation design: The sensor adopts compensation design to improve the seismic resistance of the instrument

5. Simple structure: Simple structure, no moving parts, high durability

6. Not affected by the medium: Within the specified Reynolds number range, the measurement is not affected by the temperature, pressure, and viscosity of the medium

7. Good safety: The flow meter can be used in explosion-proof occasions, with good safety

8. Wide range ratio: Wide range ratio, up to 10:1, 15:1
