High Accuracy China Vortex Flowmeter Vortex Liquid Flow Meter
Suppliers
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.
Features
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.
