Precision Vortex Flow Meters
for Steam, Gas & Liquid
Factory-direct manufacturer of vortex, electromagnetic, ultrasonic, turbine, Coriolis and thermal mass flow meters. Built to hold ±1% accuracy in demanding industrial process conditions.
LUGB Vortex Flow Meter
Vortex Flow Meters Built for Real Industrial Conditions
From saturated steam in pharmaceutical autoclaves to natural gas in city distribution networks, our LUGB and LUXB vortex meters deliver reliable performance where rotating and diaphragm meters fail. No moving parts. No clogging. Minimal maintenance with long service life.
Standard Vortex
Steam, gas & liquid. DN15–DN400. Multivariable temp/pressure compensation available.
Precession Swirl
Optimized for natural gas custody transfer. Wide turndown to 70:1. CNEX explosion-proof option.
- ✓ Measure steam, gas and liquid with a one meter
- ✓ Wide turndown ratio (10:1 to 30:1) for variable flow applications
- ✓ Multivariable models with built-in T/P compensation for direct mass flow
- ✓ Explosion-proof CNEX versions for hazardous areas
One Source for Every Flow Measurement Need
From a single vortex meter to a full instrumentation package, we manufacture 14 flow-meter product lines covering steam, gas, liquid and mass flow.
