Turbine Flowmeter Wiring


For technical parameter and connection terminal diagram for Type LWF-P-1 pulse output pre-amplifier, see Figure 8-1.

 (1) Through thread M14*1, Type LWF-P-1 pre-amplifier is screwed into installation thread holes on the body of the turbine flow meter, and then is locked with locknuts.It is a kind of small-sized amplifier of low driving power, suitable for application in association with normal display instruments.

The output signals are delivered by the connector plugs through 3-wire shielded cable, with metal shielded network grounded. The connection is as per Figure 8-1.
