SERIES OVAL ROTOR FLOWMETER
This range of
positive displacement flowmeters offers an economical means of measuring high
or varying viscosity liquids.
Cost effectiveAccurate readings
Independent of viscosity
Mechanical or LCD totaliser
Aluminium, PPS or s/s body
High pressure capability
Suitable for intrinsically safe areas
The M Series oval rotor positive displacement flowmeters
will measure your high or varying viscosity liquids.
The body takes high
pressures and is available in either aluminium PPS or stainless steel. The
meter can be supplied with a low cost mechanical totaliser or an LCD display
mounted on the top of the flowmeter. There is a pulsed output option that can
be used for a remote display or converted for transmission to a separate
control system. Apollo have a range of instruments to suit all your
The rotors are either ryton (PPS) or stainless steel making
it suitable for a wide range of fuels, oils and chemicals.
The signal can be used for a local display, remote
display or converted for transmission to a separate control system. Apollo have
a range of instruments to suit all your requirements.
Principle of Operation
The M Series operates on the oval rotor principle. Two
oval rotors rotate on stainless steel shafts and sweep the measuring chamber.
Each revolution of the rotors measures a precise volume of liquid through the
meter. This volume is independent of the viscosity and density of your liquid.
Up to three reed switch volt free contacts can be added
to the flow tube. A magnetic float is used to close the contacts on passing
them with increasing flow. The contact will remain latched until the flow
causes the float to drop below the contact and open the switch. The contacts
are rated at 240V 5A max.
The flowmeters are individually calibrated on water. We
provide you with a test certificate for each meter showing the number of pulses
per litre, which is used to set the instrumentation.
You can mount the flowmeter either horizontally or
vertically and can use it in either pumped or gravity feed applications. An
upstream filter is recommended to prevent particles damaging your flowmeter.
