Turbine Flowmeter

1, meter installation flange connection, threaded connections and clamp-on; 2, the installation of liquid flow direction should be consistent with the sensor housing indicates the flow direction of the arrow, and the upstream straight pipe should ≥6DS, downstream straight pipe should ≥5DS ( DS was measured for the pipe diameter). 3, the sensor should be away from the external magnetic field, if not avoided, should take the necessary measures; 4, in order not to affect the maintenance of normal transmission fluid, you should install a bypass pipe (Figure IV) at the outer ends of the straight pipe sensor; 5 When the sensor outdoor installation, please do waterproof amplifier plugs; 6, sensor and display instrument wiring, should be selected according to the power amplifier wiring, see the related "Instruction Manual." Six, models and specifications: LW X X- XXX XX LW expressed turbine flow sensor; XX: GY represent remote display type; Y represents the scene display type; GB, said transmitter; XXX: turbine flow sensor represents caliber; XX: Ex-B represents; E represents clamp-on; eg: LWGY-50-BE: expressed diameter of 50mm, explosion-proof, clip-mounted turbine flow sensor; LWGB-50: expressed diameter of 50mm, turbine flow transmitter.
