Nixon NT series Turbine Flowmeter

The Nixon NT series Turbine Flowmeter is available in a wide range of body sizes and styles to suit liquid flow applications for low to medium viscosity fluids. Suitable for lubricating and non-lubricating liquids, the Nixon NT series Turbine Flowmeter produces an electrical pulse output.


The principle of operation is based on a permanent magnet, which is contained within a pick off coil on the body and a ferritic stainless steel rotor which revolves when flow is present. A small a.c. voltage is generated in the coil as the rotor tip passes the  magnet.


The frequency of this a.c. voltage is directly proportional to the flowrate and the total number of pulses produced represents the total flow passed through the meter.


This pulse frequency output can be displayed either on direct mount or remotely mounted Nixon Flowmeter display and totaliser to provide flowrate indication, total flow, and allow remote batch control with electromechanical relay options.

Electronic frequency to analog converters are also available on request if 4…20mA or voltage outputs are required.


The Nixon NT series Turbine Flowmeter is highly accurate and reliable, with  a fast response time to step changes (50ms for 50% change in flow rate). Suitable for flowrates from 0.5…..10000l/min, the NT series is available with either BSP threaded connections or ANSI, DIN or BS standard flanges from 1/2″ to 6″. The maximun pressure is only limited by end fittings.


PTFE/Carbon filled or Tungsten carbide spindle bushes, and tungsten carbide spindles allow free rotation of rotors, although inherent drag on rotors means this product is not suitable to measure below 0.5% of flow range.
