Piezoelectric / capacitance vortex Flow meter
LUGB and LUGE vortex street flowmeter


Medium measured: gas, liquid, steam
Application: Measure medium volume flow or mass flow, can indicate transient flow rate and total flow, medium temperature and pressure
Signals: LCD display, pulse output, current output, RS485 or Hart selectable
Integrated switching output - Used as limit contact or pulse output
Accuracy: +/-1%, +/-1.5 %( 0.5, 0.2% is negotiable)
Installation: Have pipe type (flange or wafer connection) and insertion type
Instrument structure: combination and split type
Medium temperature: - 40 °C ~ 250 °C, 350 °C or higher
Working principle:
Vortices occur alternately and regularly to the right and left under a given condition downstream of an object (delta shape bluff body) placed in the flow. This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.

Physical parameter

Nominal diameter: LUGB filled vortex flow meter Φ10-Φ500

LUGB-J plug-in type vortex flow meterΦ200-Φ2000

Measuring fluid: liquid, gas, saturated vapor, super-heated steam

Standard condition: P=0.101325MPaT=20°C

Suitable environment temperature: -20°C~+55°C

Atmospheric pressure: 86KPa~106KPa

Relative humidity: 5%~95%

Fluid temperature: for pipe vortex flow meter:-40°C~+42; For plug-in vortex flow meter: -40°C~+250°C

Pressure class: PN 1.0MPa;PN1.6MPa;PN2.5MPa;PN4.0MPa

LUGB clamp-on vortex flow meter's flanges pressure are all PN2.5MPa, and their direct flange-connecting are PN1.0MPa pressure flange.

And LUGB-J plug vortex flow meter's flanges are all PN1.6Mpa bearing pressure as normal when out of factory. So if the needed pressure is larger than the stated pressure, advanced notification is necessary.

Accuracy class: LUGB 1class, 1.5class (0.5% and 0.2% can be negotiation)

LUGB-J 2.5% (1.5% and 1.0% can be negotiation)
