Introduction
Vortex flowmeter is a flow meter operating with Karman Vortex Street principle for flow rate of gases (air, oxygen, nitrogen, coal gas, natural gas, chemical gas, etc.). It could be used in automatic control system as flow transmitter. The product adopted advanced differential technique, together with measurement of isolating, shielding and filtering, it had possesses better anti-vibration performance and signal stability.
Features
1. Detecting element does not touch with flow medium, with high reliability and strong flexibility for medium
2. No moving parts, wear resistance, structure is simple and fastness
3. Assemble with anti-interference circuit and anti-vibration sensors, which could ensure anti-vibration performance of the product.
4. The allowed working temperature is wide from -40℃ to +350℃
5. Wide range, High accuracy
6. Pulse signal output or two-wire system 4-20mA current signal output
