3. MODEL AND SELECTION
 Performance
 4.1  Turbine Flow Sensor/Transmitter
 LWQ-C Type  Sensor:12 to 24V DC Power Supply;Pulse Output
 LWQ-F Type Transmitter:24V  DC Power Supply;2-wire,4 to 20 mA Output
 Basic Type(Without  Explosion Proof) and Explosion Proof Type are optional for LWQ-C and LWQ-F.
                              

                   Basic Type                                           Explosion Proof Type
 4.2  Intelligent Integrated Turbine Flow Meter
 ◆4 digital  instantaneous flow display
 ◆8 digital  totalizator flow display(Resettable)
 ◆With Explosion  Proof(Level:ExdIIBT6)
 ◆3-Point  Correction and Non-linearity Compensation on K-Factor
 Note:The K-Factor represents the  number of output pulse transmitted per cubic meter(Optional:Liter and Gallons)  of Fluid passing through the turbine meter.Each turbine has a unique  K-Factor.However,turbine meters are not functionally consistent throughout the  full flow range of the meter.Therefore,correction and non-linearity  compensation on K-Factor can enhance accuracy.
 LWQ-Y Type:Powered  with 3.2V 10AH lithium battery(Battery life＞4  years);no output
 LWQ-B Type:24V DC Power  Supply;2-wire 4~20mA Output(Optional:RS485 or HART)
 LWQ-B1/B2 Type (With temperature and pressure compensation):  24V DC Power Supply
