Main application
DBLU vortex series flowmeter mainly applies the Karman vortex principle,
A speed meter using a stress-type piezoelectric crystal sensor,
For flow measurement of gases, liquids and steam,
There are ordinary type, high temperature type, intrinsically safe explosion-proof type, explosion-proof type, plug-in type and other series of products.
It can be applied to industries such as metallurgy, electric power, chemical industry, petroleum, light industry, environmental protection and municipal construction.
Main Features：
Main Features：
Wide range, high accuracy, low pressure loss, high reliability and long-term stability
Simple structure, easy installation and maintenance, no moving parts, no mechanical wear
There are two output signals, pulse and analog. The signal is only proportional to the flow rate of the measured medium, and has nothing to do with the temperature, pressure, viscosity, composition, etc. of the measured medium. There is no zero drift problem.
The sensitive element is encapsulated in corrosion-resistant material and does not come into contact with the measured medium, which has the advantages of a solid sensor
The small sensor is independently installed behind the vortex generator, which reduces the influence of dirt in the medium and the influence of pipeline vibration
