Description

Interface Meter

Model 122
Solinst Oil/Water Interface Meters give clear and accurate 
measurements of product level and thickness in wells and tanks.
Determination of both light (floating) non-aqueous phase liquids
(LNAPL) and dense (sinking) non-aqueous phase liquids (DNAPL) is quick and easy. The factory-sealed probe is pressure proof (up to 500 psi) and tapes are available in a range of lengths from 30 – 300 m (100 – 1000 ft).
The 16 mm (5/8″) diameter probe allows easy access through
tight spaces and into narrow wells. The probe is designed for use in various monitoring applications. 122M Mini Interface Meters also available, see 122M Data Sheet for more information.

Hazardous Locations Use
Model 122 Interface Meters have been approved for use in
explosive environments. They are suitable for use in hazardous locations Class I, Div 1, Groups C&D based on standards of the Canadian Standards Association (CSA).
The Model 122 Interface Meter with laser marked tape
is now ATEX certified under directive 94/9/EC, as II 3 G Ex ic
IIB T4 Gc.

The grounding strap is a safety essential when the meter is used
in potentially explosive environments. It also ensures that the electronics are properly protected.

Operating Principles
Product
(Non-conductive liquid) = Steady light and tone
Water
(Conductive liquid) = Intermittent light and tone
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 conductive (water), the conductivity of the water completes a conductivity circuit. This overrides the infra-red circuit, and the tone and
light are intermittent.

The 122 Interface Meter sensor
provides an accuracy as good as 1.0 mm or 1/200 ft. The high accuracy enables the sensor to detect the slightest sheen of oil on the surface of the water.

Accurate, Reliable, Robust
Designed for rugged field use
Stable electronics with automatic circuitry testing
Laser marked flat tape is easy to decontaminate; resists stains
Tape uses stranded stainless steel and copper coated
steel conductors:

– high in tensile strength; electrical efficiency

– non-stretch; does not corrode

Sturdy free-standing reel with carrying handle

High Quality Design
The state-of-the-art electronics include automatic circuitry testing
when the ‘On’ button is used; 120 hours of on-time battery life; clear signals; and high accuracy. The circuits are powered by a single standard 9V battery which is housed in an easy-access drawer in the faceplate of the reel.
Infra-red refraction is used to detect liquids and conductivity
to distinguish water. Both optical and electronic sensors are precisely aligned at the same zero point. The factory sealed probe does not need to be accessed by the user. An integral stainless steel shield protects the sensors. It is set permanently into place, yet allows for easy cleaning.

Features
Sensor accuracy to 1.0 mm or 1/200 ft
Certified intrinsically safe
16 mm (5/8″) diameter probe
Easy access 9V battery
Automatic shut off after 5 minutes
Replacement tapes are interchangeable with other Meters
