Tosilon Digital Vortex Flow Transmitter for Water (Ex Approved)
Design and Manufacturing according to CE Standard


- TVF58 series Intelligent Vortex Flowmeter include TVF580, TVF581, TVF582.
- TVF580: 2-wire (24 VDC), 4~20ma, pulse output.
- Refer TVF580 manual for detail.
- TVF581: Temperature and pressure compensation
- 2-wire (24 VDC), 4~20ma, pulse output.
- Refer TVF581 manual for detail.
- TVF 582: Steam saturation, lithium battery, display total. Refer TVF582 manual for detail

Measuring Principle

The flowmeter is based on kormaon's vortex street theory. When the liquid pass non-streamlined barrier, alternative vortex signal will be generated on both sides of the barrier.
Piezocrystal, as the transmitter will check the signal; The analog circuit and digital circuit will convert it to current, pulse signal output in positive proportion with flow rate. The total will be clearly displayed.


· Simple Structure
· No Moving Part
· Reliable
· Durable with one Echelon Vortex Generator
· Output is proportional with flow rate
· The two pieces piezoelectric components are used to tests the vortex being not contact with the medium
· Liquid, gas and vapor could be measured by transmitters with same structure
· The mediums under all temp. And pres. Could be measured
