46. te The bearings in your flowmeter have been selected by our staff based on what we have found to be the best choice for your application FLOWMETER PICKUP SELECTION The flowmeter pickup senses the motion of the rotor and converts it to a pulsing electrical signal which 1s of a discrete digital nature Hoffer Flow Controls offers several pickup types suited for different applications The advantages of each are listed HIGH OUTPUT MAGNETIC PICKUP TYPICAL RANGE 10 1 The standard pickup for turbine flowmeters larger than 1 inch produces a high level sinusoidal output To produce this the pickup generates a relatively high magnetic field The signal may be transmitted up to 200 feet without amplification A flow range of 10 1 or better is common with this pickup type HP 228 Turbine Flowmeter Manual Page 3 LOW DRAG MAGNETIC PICKUP TYPICAL RANGE 25 1 Low drag magnetic pickups may be used to obtain a flowmeter range of 25 1 or better They offer a significant reduction in drag effects with lower output levels and may require pre amplification prior to transmission Low drag magnetic pickups are used extensively in meter sizes below 1 inch MAGNETIC PICKUP OUTPUT SIGNAL CHARACTERISTICS The output signal voltage of the magnetic coil is approximately sinusoidal The frequency range of the pulsing signal varies from meter size to meter size However standard ranges allow for maximum output frequencies at the nominal linear flow of 25
