The Series 1750 range of Variable Area
Flowmeters are ideal for providing instanta-
neous flow rate measurement for most
process gases and liquids. The standard
models are suitable for flows up to 50 lit/min
on liquids and 1750 lit/min on gases @ STP.
These units feature a calibrated metric scale of 100mm which
is permanently fired on the tube, although a useful blank scale
plate can also be provided for customers requiring their own
Materials of construction ensure compatibility to a wide range
of industrial process mediums and applications, end connec-
tions can be supplied in brass, stainless steel, or rigid PVC.
They can be fitted with Hi and Lo latching alarms, including
an economical latching alarm which enables the alarm to
remain activated whilst flow is above or below a set point.
This reduces expensive electronic circuitry and is ideal for
remote process control applications.
