NT Industrial Flow Meters
Standard end connections are screwed BSP parallel thread with included 30 degree internal cones to BS5200, but Ermeto threads are also available. Flanged meters are normally to ANSI 150 or BS4504 (DIN) standards, but older type flanges to BS10 tables D-H may also be fitted. 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 flow rate, rising to 800mV peak at max flow rate. 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.
- Temperature range -30°C to 150°C (400°C special design)
- Horizontal or vertical mounting
- Upto 500m transmission without pre-amplifiers
