Platon NS Series Pelton Wheel  
Flowmeter  
DS1010  
Features:  
Measuring Range: 8 to 1  
Accuracy: ±1.0%  
Repeatability ±0.25%  
Operaꢀng Temperature: 150˚C max  
Operaꢀng Pressure: limited only by coupling design  
Transmission length: Up to 300 meters  
Overall length: Flanged 114mm Screwed 95mm  
Descripꢀon:  
A turbine flowmeter operaꢀng on the Pelton wheel principle for low flowrate applicaꢀons on low  
viscosity fluids.  
Convenꢀonal axial flow turbine meters become increasingly difficult to manufacture in very small sizes  
and bearing drag becomes more significant. The Pelton wheel on the other hand sꢀll retains a  
manageable diameter allowing close machining tolerances whilst being capable of handling very low  
flow rates with reasonable accuracy.  
The units may be used for addiꢀve flows, fuel consumpꢀon metering, perfumes, colourings etc. With  
this design a range of interchangeable metering plugs may be provided within one body size, such that  
flow ranges may be changed very simply.  
Construcꢀon is in stainless steel as standard but other materials may be used to suit the corrosive  
properꢀes of the metered fluid. Flanges to ANSI, EN1092-1 or BS10 may be fiꢁed and a design is also  
available with Ermeto or BSP couplings for high pressure hydraulic work.  
Operaꢀng Principle:  
In operaꢀon a star shaped paddle wheel is housed  
within a metering plug containing a small jet hole  
such that a high velocity jet is imparted tangenꢀally  
on the rotor. Rotaꢀonal speed and hence frequency  
are directly proporꢀonal to flowrate. The sharp  
edges of the rotor are detected by a reluctance pick  
off coil and an alternaꢀng voltage is thus generated.
