High Accuracy Vortex Air Flow Meter , 4 - 20mA Steam Flow Transmitter

High Accuracy Vortex Flowmeter For Steam / Air / Co2 / O2 / Offer OEM Vortex Flow Meter


Introduction


Vortex flowmeter is based on the"Karman vortex" principle, the use of piezo electric crystal as a measuring element of the flow measurement instruments for a variety of gas, steam, liquid flow measurement . LUGB series of vortex flowmeter specifications from DN15 to DN600, vortex flowmeter in accordance with the structural characteristics into full-tube vortex flowmeter and plug-in vortex flowmeter. In accordance with the different output signals can be divided into pulse output mode sensor and the standard current output of the transmitter.The instrument has the advantage of wide flow measurement range,high accuracy,simple structure, small pressure loss, no moving parts, etc.It is applied to the measurement of instantaneous flow and total flow of fluid in a closed pipeline.


Structure vortex flow meter

Features


Measurement is independent of fluid density ,viscosity,humidity, temperature pressure and conductivity There are no obstacle parts in the measuring tube no pressure loss to the tube of which the straight part is of low requirement The sensor with grounded electrode gurantees the grounding wellThe sensor with advanced processing technology is of nice resistance to the negative pressure.
1. Simple and firm, no moving parts, high reliability, long-term operation is very stable
2. Zero drift, high precision
3. Pressure loss is small, easy to maintain
4. Measuring range, range up to: 1: 15
5. Wide range of applications, gas, liquid, steam flow can be measured
6. Wide operating temperature range: -40 ℃ to 350 ℃ high temperature
7. Output pulse signal or current signal, easy to use with computer and other digital systems
