LWGY Liquid Turbine Flow Meter
The Apure LWGY is a liquid turbine flow meter that uses rotor speed to measure volumetric flow. Its pulse output can feed a compatible indicator, totalizer or controller configured with the calibration factor for the supplied meter.
- High precision, good repeatability
- Electric pulse signal output, wide range
- Anti – electromagnetic interference anti – vibration ability
The liquid drives a rotor and a pickup produces pulses as the rotor turns. Within the calibrated range, the pulse frequency indicates flow rate. When the K-factor is expressed in pulses per unit volume, accumulated pulses divided by K give the accumulated volume in that unit. Use the K-factor from the supplied calibration data and confirm its units before programming the receiver.
Installation and selection
Select the meter for the liquid viscosity, solids content, operating pressure and temperature, and expected flow. Confirm a full pipe and the required upstream and downstream piping. Check whether filtration is needed for the selected meter and process. Entrained gas, deposits and rotor or bearing wear can affect the reading. Confirm the supplied pulse interface, power requirements and permitted cable arrangement.
Inspect the rotor and bearings according to the supplied maintenance instructions. Check pulse output and calibration after service. Confirm the permitted liquid temperature for the selected body material and use the cable requirements for the ordered signal arrangement.
