1.2 Introduction
ISOIL positive displacement meters are precision measuring instruments designed for use
with a variety of petrochemical products and liquids. Each meter is fully tested and calibrated
by factory before dispatch, and a regular service will maintain a high standard of
performance and accuracy.
P.D. meters must be periodically tested by a calibrating tank, Prover, or Master Meter: if out
of accuracy a service is necessary.
Experience has shown that mechanical defects are usually caused by the entry of foreign
matters into the metering compartment due to inadequate straining facilities in the pipeline.
Special tools have been designed to facilitate overhaul operations and their use is
recommended. Reference to the tools is included in the next pages (see chap.5).

1.3 Working principles
Liquid enters the meter through the manifold and causes the rotor to revolve by pressure on
the vanes. The proximity of the rotor to the front and rear of the casing forms an efficient seal
while the profile of the casing guides the vanes on to the measuring crescent.
