The Solinst Oil/Water
Interface Meters give accurate measurements of product level and the thickness
in wells and tanks. Determination of both floating non-aqueous liquids (LNAPL)
and sinking non-aqueous liquids (DNAPL) is quick and easy. The Model 122
Interface Meter has been approved by the Canadian Standards Association (CSA)
for use in explosive environments.
How does the Solinst
Interface Meter work?
To detect liquids,
Solinst Interface Meters use an infra-red beam and detector. When the probe
enters a liquid the beam is refracted away from the detector which activates
an audible tone and light. If the liquid is a non-conductive oil/product the
signals are steady. If the liquid is water, the conductivity of the water
completes a conductive circuit. This overrides the intra-red circuit and the
tone and light are intermittent.
Both sensors use exactly
the same zero point giving accuracy as good as 1/100' or 1mm. The circuits are
powered by 2 standard 9V batteries (one for the Mini) which are housed in easy
access drawers on the faceplate of the reel.
