Low Pressure Loss And Low Wear Steam Vortex Flowmeter
Vortex flow meter 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
When the vortex flowmeter installed after the pressure reducing valve, the wet saturated steam suddenly more substantial decompression, adiabatic expansion of the fluid, the evaporation of the water droplets, while absorb the heat of vaporization from the liquid and vapor phase, the temperature of the vapor liquid decreases. If the temperature reduce not much or high humidity before evaporation, it will quickly reduce the temperature to the new pressure corresponding to the saturation temperature, and establish a new balance, now the steam is still saturated steam; If the pressure reduce so much or the low humidity before evaporation, because of the droplet evaporates, the temperature is still more that the saturation temperature corresponding to the new pressure.
