accurately measure the mass flowrate, density and temperature of liquids,
suspensions, emulsions and gases.

These are very accurate for dosing and batching of
liquids and gases. They cover the range from 0.01kg/min to 3000 kg/min. The
results are accurate independent of changes in viscosity, temperature, pressure
The display converter has an LCD display. It displays the
mass flow rate, total, temperature and density. It has pulse and current
outputs for a wide range of control systems.
Principle of Operation
Coriolis forces are generated in an oscillating system
when a mass moves away from or towards an axis of oscillation. The measuring
tube is vibrated at a uniform frequency. With no flow the Coriolis force is
zero. During flow the particles in the fluid are accelerated and decelerated to
and from the axis of oscillation. This generates Coriolis forces that move the
measuring tube by extremely small amounts and are detected by special sensors.
The Coriolis force is directly proportional to the mass flowrate.
The range of materials of the wetted parts make it
suitable for almost all applications.
The flowmeters consist of a detector
and a display converter. They can be supplied integral with the display mounted
directly on the detector or separately connected by cables (100m max.) so the
display can be mounted remotely.
There is an option for a heating jacket
fitted to allow the line fluid to be heated up to 150 oC. For this option the
converter must be mounted separately.
Each flowmeter is calibrated against scales. The scales
are calibrated to National Standards by the Trading Standards Calibration
The mass flowmeters have measuring errors of less than 0.15% of
the measured value.
To ensure accuracy over the measuring range,
calibrations are carried out at different flow rates.
Each mass flowmeter
is also calibrated for a density range of 0.5 to 2.0 g/cm3.
The flowmeter is mounted in the line and should be
maintained full of liquid prior to and throughout measurement. You are strongly
advised to avoid heavily vibrating environments. The tube can be installed in a
vertical or horizontal line and has a straight through bore that is
self-draining and has a minimal pressure drop. A zero point calibration is done
after installation when the line is full of liquid.
There is a range of equipment for use with the S series
flowmeters. These include air eliminators, check valves, filters and
