The Lowflo flowmeter is used to measure extremely low flow rates of clean liquids, chemicals, additives, demineralised water, oil and fats. Applications include dosing of chemicals, batching, injection into food and animal feeds processes, blending, monitoring and pH adjustment.
The pulse from the flowmeter is fed into an instrument and can be used for flow rate indication, totalising, blending, dosing, controlling and batching. The flowmeter can be used in hazardous areas. Apollo provide a range of instruments to suit your application.
Principle of Operation
The PFA Pelton wheel rotor has stainless steel rods embedded within the tips of the vanes. Tungsten carbide balls are integral to the rotor. The tungsten balls of the rotor spin in sapphire cups mounted in stainless steel bearing housings. The flow of liquid causes the rotor to turn and a proximity sensor detects the passing of the rotor tips. The speed of the rotor and the frequency of the signal is directly proportional to the flow rate.
