Titan's own product range are all based on the Pelton wheel technique.
This well proven method is the ideal way of measuring low
rates of flow of low viscosity liquids. Our comprehensive
ranges of radial flow turbine meters offer a selection of
products for many differing types of application. Some are
suitable for chemical plant others for the semi-conductor
industry and others are ideal for drink dispense or beer monitoring
equipment. All have rugged bearings and excellent repeatability.
The choice of fitting type reflects the function of the meter,
some have simple hose barbs and others may be fitted with
custom designed process connections to suit a OEM installation.
Classic turbine flow meters simply use Propeller type turbines in
a closed circular conduit. The turbine is mounted on low friction
bearings and its rotation is detected through the chamber
wall by one of a variety of detector types. These meters have
excellent linearity in larger sizes but as the pipe bore reduces
the efficiency of the meter also reduces. The bearing properties
become even more important as the drive torque is greatly
reduced relative to the bearing drag, this results in a lower
linearity device in small sizes. Our small turbines use a
radial flow principle sometimes referred to as “Pelton
wheels”. This is not strictly true as a Pelton wheel
is designed with reaction cups to remove power from a water
jet and our devices are designed to have a rotational speed
that is linear to fluid throughput.
For the smaller sizes a jet of fluid is directed at a turbine
that is mounted on robust low friction sapphire bearings.
The geometry of the turbine and the fluid chamber ensures
that the rotational speed of the rotor is proportional to
the flow rate through the device. The use of this radial
arrangement allows more energy to be imparted into the turbine
so the bearing drag is far less important. Further more;
because more energy is available the bearings themselves
can be a lot stronger so increasing the life of the flowmeter.
For larger flows some of the fluid can bypass the turbine
chamber, which then behaves as a “shunt” to
the metered fluid, accuracy is still maintained and the
output remains linear.
