3. When measuring flammable liquids, observe
precautions against fire or explosion.
4. When working in hazardous environments,
always exercise appropriate safety precautions.
1. Use only fluids that are compatible with the
housing material and wetted components
of your Vortex.
2. When handling hazardous liquids, always
exercise appropriate safety precautions.
5. Handle the sensor carefully. Even small
scratches or nicks can affect accuracy.
Stress-type vortex flow meter is a speed flow meter, widely used in petroleum, chemical,
power, light industry, power, heating and other industries.
During Vortex removal, liquid may spill.
Follow the manufacturer’s safety
precautions for clean up of minor spills
For best results, calibrate the meter at
least 1 time per year.
For your safety, review the major warnings and cautions below before operating your
equipment.
LUGB series Vortex flow meters are 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, LUGB series 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.
The basic structure of the vortex flow meter is shown in Diagram 1. It is mainly composed of
body, probe, vortex generator, meter rod, condenser pipe and converter.

Pipes must be fully filled with liquids. It is essential that pipes remain fully filled at all times,
otherwise flow rate indications may be affected and measurement errors may be caused.
Warning:Precaution for direct sunshine and rain when the meter is installed outside.
Flow altering device such as elbows, valves and reducers can affect accuracy. See
Install the meter with enough room for future access for maintenance purposes

★
★ Downstream: allow a minimum straight pipe length at least 5 times the internal diameter of
the pipe. For example, with the 50mm pipe, there should be 250mm of straight pipe
immediately upstream. Desired upstream straight pipe length is 500mm.
The recommended guidelines are given to enhance accuracy and maximize performance.
Distance given here are minimum requirements; Double them for desired straight pipe lengths.

Special Notice
★ When the fluid is liquid, to ensure accurate measurement, drain all air from the system

Formula 1: Pb ≥ 1.25×Pv + 2× (Pin – Pout)
In formula 1: (Pb: Back pressure; Pv: Vapor Pressure; Pin: Inlet Pressure; Pout: Outlet Pressure)
Create backpressure by installing a control valve on the downstream side of the meter at the
proper distance detailed above.
When the meter contains removable coverplates. Leave the coverplate installed unless
accessory modules specify removal. Don’t remove the coverplates when the meter is
powered, or electrical shock and explosion
Cavitation can be caused by entrained air. An amount higher than about 100 mg/l of entrained
air or gas can produce error. In addition, cavitation can be caused by too little backpressure
on the flow meter. For our Vortex flow meters, you should provide a backpressure (downstream
flow meter. See formula 1.
