LUGB-Series Vortex Flow Meter
Size of flow meter
Chart of flow meter
- Feature
- Piezocrystal inbuilt in bluff body to avoid fluid turbulance caused by external type, no zero drift and high reliability
- No moving parts, high durability
- Convenient installation and maintenance
- Sensor not connect with the measured fluids directly, stable performance and long service life
- Output pulse signal is directly proportional to flow rate, high accuracy and no zero drift
- Wide measuring range, turndown ratio 10:1
- Low pressure loss, low cost
- Frequency output not affected by the fluid change in physical character and composition, meter factor (K) only considers shape and dimension of eddies. Measurement of volumetric flow can get compensation once it needs. Then no re-calibration meter factor needed if damaged parts be exchanged
- Wide application for air, gas.
