LOWFLO FLOWMETER    

The Lowflo uses the Pelton wheel principle to measure the extremely low flow rates required in laboratories, research establishments and process plants. It will cover flow ranges from 1 to 420 litres/hour.


High accuracy and repeatability
Well proven and long life bearings
Easily maintained
Access the internals without removing
the body from the line
Robust stainless steel construction
Withstands high pressure and temperature
ATEX intrinsic safety approval
Individual calibration certificate

Application
The Lowflo flowmeter is used to measure the extremely low flow rates of clean liquids, chemicals, additives, demineralised water, oil and fats. Applications include dosing of chemicals, injection in to food and animal feeds processes, batching, blending, monitoring and pH adjustment.

Instrumentation
The output frequency 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 PVDF or PFA Pelton wheel rotor has steel rods embedded within the tips of the vanes. Tungsten carbide balls are mounted into the rotor. The rotor and tungsten balls spin in sapphire cups mounted in s/s 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.

Construction
The Lowflo has a strong stainless steel body that is corrosion resistant and withstands high pressures. The flowmeter is designed for use on clean liquids although particles up to 200 micrometres can be entrained in the liquid without any effect on the overall performance. The two wire Namur sensor is fitted into the headcap of the flowmeter and is supplied with a 2 metre length of cable for connection to remote instruments.

Calibration
All Lowflo flowmeters are individually calibrated with water and are traceable to national standards.We provide you with a test certificate for each meter showing the number of pulses per litre, which is used to set the instrumentation.

Intrinsically Safe Version
The flowmeter can be used in Intrinsically Safe areas. The sensor is certified to ATEX II I G EEx ia IIC T6.

Installation
To get the best results from your flowmeter it should be mounted into the pipework with its sensor lying horizontally. The flowmeter should be maintained full of liquid prior to and throughout measurement.
