BNO Hygienic Turbine Flowmeter
Quick Spec:
Minimum of bacteria breeding crevices.
Easy one circlip dismantling
Strong rotor design
Wide variety of end fittings available
The BNO series flowmeters have been designed specifically for high accuracy flow measurement and batch control in the liquid food industries, and conform to the same exacting standards as our NT industrial flowmeters so far as performance is concerned.
In the basic design, Nixon Flowmeters have been aware of the particular hygienic requirements of pharmaceutical industries and great care has been taken to ensure the absence of crevices where bacteria can lodge and breed.
The materials used in construction ensure that no corrosive attack occurs when in-place cleaning agents are used.
More Info
Manufactured entirely from stainless steel, except the bearing bushes which are normally of PTFE/Carbon. There are no seals or ‘O’ rings, nor any internal screw threads. Rotors are machined from solid, and bearing supports (hangers) are stepped in order to reduce the contact area between hanger and meter internal bore.
Advantages
A ferritic stainless steel rotor revolves within a nonmagnetic housing on the outside of which is located a pick off coil containing a permanent magnet. As the rotor blades pass the tip of the permanent magnet, the reluctance of the magnetic circuit is changed, and a small a.c. voltage is generated in the coil. The frequency of the a.c. voltage is proportional to flowrate, and the total number of pulses produced represents total flow passed through the meter.
The flowmeter may be located some considerable distance from the associated secondary instrument, and remote flowrate indication, total flow, and most important remote batch control are thus possible.
