The Nixon range of turbine flowmeters offers high accuracy and high reliability. Over 50 years, thousands of units have been sold to all classes of industry, and the meters have an excellent reputation for durability.
Many leading flowmeter companies in the U.K. and abroad have the confidence to put their name on our range of turbine flowmeters, a sign of the high regard in which the product is held.
The range has been modified and extended over the last few years to provide a reasonably priced general-purpose flow transmitter. We produce the units entirely in-house to control quality and availability.
The range is available on short deliveries, and popular sizes are held ex-stock.
Product Details
Contact parts are produced from 316 stainless steel,except rotors which must possess good magnetic qualities, and here 431 stainless is used or Ferralium alloy depending upon the corrosive properties of the liquid.
Standard end connections are screwed BSP parallel thread with included 30 degree internal cones to BS5200, Ermeto threads are also available.
Flanged meters are available with ANSI, DIN or BS standards
A unique feature of the design is the use of helically milled rotors cut from solid in sizes up to 65mm.
Bearing bushes are of PTFE/Carbon HY49 or similar, or tungsten carbide depending upon the nature of the metered fluid. In all cases, the spindle is of tungsten carbide with Cobalt binder, and thrust balls of tungsten carbide. Stainless steel ball races are used in the smaller sizes.
The electrical signal is a sinusoidal pulse of minimum height 50mV peak at lowest flowrate, rising to 800mV peak at max flowrate. For normal transmission distances pre-amplifiers are not essential since pulse shaping and conditioning are carried out in the appropriate electronic readout unit. In cases where heavy electrical noise is present or where transmission distances are over 500 metres, pre-amplifiers of standard or intrinsically safe design are available as head mounted weatherproof units and loop powered.
More Information
Available in a wide variety of body sizes, all NT flowmeters possess an electrical pulse output directly proportional to flowrate.
Remote flowrate indication, alarms, totalising and batch control functions are available utilising our wide range of secondary electronic instruments.
The flowmeters are suitable for use on lubricating or non-lubricating liquids of low to medium viscosity and are largely insensitive to density variations, pressure or temperature fluctuations.
