The Peltflo is suitable for a wide range of liquids such as acids, solvents, water, agrochemicals and light oils. You can use it for container filling, dispensing, flow rate indication, controlling and spraying. The flowmeter is designed for use with clean liquids although particles less than 0.25mm will be harmlessly washed through.
The output frequency is fed into an instrument. Apollo can provide you with a comprehensive range of displays and control instruments. In hazardous areas you can use the flowmeters with the Apollo I.S ATEX approved sensor. The signal can be used in the IS area or transmitted to a safe area using the intrinsically safe P5 preamplifier and suitable barriers.
Principle of Operation
The PFA pelton wheel has ferrites fitted to the tips of the vanes. Tungsten carbide balls are mounted directly into the rotor and spin in sapphire cups which are mounted in a bearing housing. The liquid flow causes the rotor to turn and the ferrites induce pulses in the sensor. The frequency of this signal is directly proportional to the flow rate.
