Operating Principle
The Solinst Model 122 Interface Meter has a narrow
5/8" (16 mm) diameter probe and uses laser-marked PVDF
flat tape. It is certified to CSA Standards, for use in
hazardous locations Class 1, Div. 1, Groups C & D T3C,
and is ATEX certified under directive 94/9/EC, as II 3 G
Ex ic IIB T4 Gc. It has an infra-red circuit which detects the
presence of a liquid. A conductivity circuit differentiates
between conductive liquid (water) and non-conductive liquid
(LNAPL or DNAPL product).
Equipment Check
Before beginning any measurements, check the electronics
and battery condition by pushing the 'START/OFF' button.
Five quick beeps with the green light flashing, indicates that the
meter is functional. A flashing green light every second indicates
the meter is on. It will automatically turn off after 5 minutes to
preserve battery life.
Using the Tape Guide
1. The tape guide has been designed to: improve accuracy
when reading interface measurements; to prevent the
laser-marked PVDF flat tape being cut by well casing; and
to allow the tape and probe to hang straight from the side
of the well.
2. If interface measurements are being taken in a 2" dia well,
then simply fit the small end of the tape guide onto the
edge of the well casing.
3. Insert the leg of the Interface Meter into the hole on the
Tape Guide (small reels only).
4. Once inserted, rest the Interface Meter on the side of the
well casing.

• To adjust your
measurements,
simply subtract

Field Measurements
IMPORTANT
1.
To meet safety requirements and to protect the
electronics from damage, always ground the meter by
attaching the grounding clip to the metal well casing or
to a suitable ground rod.
2. Push the 'START/OFF' button. Five brief tones and
green light indicate that the meter is functional and the
flashing green light indicates that the meter is on. The
meter automatically turns off after 5 minutes. Press the
'START/OFF' button as necessary during operation to
turn the meter back on.
3. Place the slotted part of the tape guide onto the edge of the
well casing. Lay the Interface Meter laser-marked PVDF
flat tape into the groove on the top of the tape guide.
Measurements are read at the V-notch on the tape guide.
Note:
When using the tape guide, remember to
subtract the compensation factor
stamped onto the side of the guide from
each measurement.
4. A steady tone and red light indicates a non-conductive
liquid (e.g. product). An intermittent tone and red light
indicates a conductive liquid (e.g. water).
5. For floating product (LNAPL), take the air/product
interface measurement on the way into the liquid, and
the water/product interface on the way up. When passing
through product into water, some product may adhere
to the probe sensors due to surface tension. Therefore,
when water is detected below product, the probe should
be raised and lowered rapidly in a short vertical motion to
remove any product that may have been carried down with
the probe.
