Thread Turbine Flow Meter

Description  of  products
I Outline
HLWGY series Turbine Flowmeter has simple structure, high accuracy, good repetitiveness, fast response and
convenient maintenance. It is widely used for liquid without corrosion to stainless steel, Al2O3 or hard alloy, without
fibre or particle and kinematic viscosity less than 50×10-6m2/s.
II Features
1. High accuracy: ±1%, ±0.5%, ±0.2% for high accuracy
2.Good repetitiveness: 0.05% ~ 0.2%
3. Output of pulse frequency signal, suitable for totalizer and connection with PC; no zero shift and strong
interference resist
4.High frequency signal (3~4 kHz), strong signal resolution power
5. Turndown: 1:20, 1:10
6.Compact structure & convenient maintenance
Instrument Classification
1. According to instrument function, HLWGY Turbine Flowmeter can be classified to two types, that is:
(1) Turbine flow sensor/transmitter
(2)Smart integral turbine flow meter
2. Function Description
(1)Turbine flow sensor/transmitter
This product itself has no local indication function, only remote transmission of flow signal. Flow signal can be
divided to pulse signal or current signal (4-20mA); low price, high integration level, small volume, especially
suitable for using together with secondary indicator, PLC, DCS, etc. computer control system.
