4~20mA+RS485 HART output vortex gas flowmeter vortex Transmitter
Vortex flowmeter is designed for measuring the volume/mass flow of liquids, gases and steam based on Karman vortex principle. Adopting advanced differential algorithm along with measurement of isolation, shielding and wave filtering, vortex flow meters have the advantages of immunity on vibration and noise. Meanwhile, the liabilities of LUGB series vortex flow meters are well guaranteed by unique sensor packaging technology. Upon receipt, examine your meter for visible damage. The Vortex is a precision measuring instrument and should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are damaged or missing, contact us. Make sure the Vortex flow model meets your specific needs.
1.High accuracy and good repeatability
2.The detection element has no contact with the fluid, and has stable performance and high reliability.
3.The structure is simple and firm, movable parts, and reliable in long-term operation.
4.The measuring range is wide that can up to 1:10 (special up to 15).
5.The pressure loss is small, about 1/4~1/2 of the orifice flowmeter
Scope of application
It is widely used in large, medium and small types of pipeline drainage, industrial circulation, sewage treatment, oil and chemical reagents, and the measurement of compressed air, saturated, overheated steam, natural gas and other medium flow.

Cautions for installation
Rquired Lengths of Straight Run
The recommended guidelines are given to enhance accuracy and maximize performance. Distance given here are minimum requirements; double them for desire straight pipe lengths.
• Upstream: allow a minimum straight pipe length at least 10 times the internal diameter of the pipe.
For example, with the 50mm pipe ,there should be 500mm of straight pipe immediately upstream.
Desired upstream straight pipe length is 500mm.
• Downstream:allow a minimum straight pipe length at least 5 times teh internal diameter of the pipe. For example, with the 50mm pipe , there should be 250mm of straight pipe immediately upstream. Desired upstream straight pipe is 500mm.
