7010 – All Variants
Thank you
May we take this opportunity to thank you for purchasing this sensor.
The 7010 liquid level sensor is a precision measurement device designed to give accurate data over many
years of continuous operation. Observing a few simple steps will not only get the sensor up and running in
short time, but will ensure you get the best from the sensor.
We also highly recommend a visit to the Gill website www.gillsc.com/support where you can view or
download a full instruction manual and also download the GSlevel software application specically designed
to optimise operation of the sensor.

A few Do’s & Don’ts:
DO check you have the correct length of sensor for the tank, observing a minimum of 5mm clearance to the
bottom of the tank and clearance above for access.
DO check the sensor has the correct mounting ange (either 5 Bolt and 1.125”UNF, 5 Bolt & 1.25”BSP tting or
2” NPT tting) for the installation.
DO check the details to ensure you have a sensor with the correct output for your system (0-10V or 4-20mA).
DON’T attempt to cut the sensor to length or bend the sensor. Both actions will result in the sensor failing
and will invalidate the warranty.
DON’T use the sensor in a tank that is not adequately vented.
DON’T immerse the ange or cable in the liquid to be measured.
*Please note, images and diagrams in this document are for illustrative purposes only.
What you need to install this product:
1. A hole above the deepest part of the tank with the appropriate tting to match the sensor (5 Bolt,
UNF threaded, BSP threaded, NPT threaded).
2. O-ring or gasket dependant on model (supplied with the sensor)
3. PTFE or pipe sealant dependant on model (not supplied)
4. 5 x M5 bolts & xings (length dependant on tank wall thickness)
5. Adjustable spanner (50.0mm A/F for NPT version)
6. Torque wrench
Fitting the Sensor:
There are four dierent options for installing the sensor into the tank with three methods of sealing them.
These are as follows;
• 5 Bolt SAE mounting using the supplied gasket to seal the tank.
• 1.125” UNF threaded mounting with either the gasket or O-ring
• 1.25” BSP threaded mounting with either the gasket or O-ring
• 2” NPT threaded tting with either PTFE or pipe sealant.

SAE 5-Bolt tting
The sensor should be tted with the supplied gasket (see Fig 2).
Place the gasket black side up on a cleaned mounting surface,
position the sensor and t and tighten the xing bolts (Fig 1) to
a torque of 10Nm.
Gasket tting
Prepare a hole in the tank according to the tting type, UNF or
BSP (see Fig 3).
Fit the gasket on the cleaned mounting surface, with the black
side facing upwards (see Fig 2). Tighten the sensor using a
59.5mm A/F spanner to a torque of 50Nm.
O-Ring tting
Prepare a hole in the tank according to the tting type UNF or
BSP (see Fig 4).
Fit the O-ring over the mounting thread so that it is sitting in
the groove on the underside of the sensor ange (see Fig 5).
Tighten the ange using a adjustable spanner to a torque of
50Nm.

Tapered NPT sensor tting
Fitting the NPT sensor does not require the use of either the
O-ring or gasket. NPT ttings use a tapered thread design to
seal the threads rather than the sealing surfaces around them
(see Fig 6).
Apply PTFE or pipe sealant to the threads and tighten using a
50.0A/F spanner.
Electrical Connection
Once the sensor is installed in to the tank, connect the sensor
using the diagram below.
Optimising Sensor Operation
For further adjustment over the set up, download the GSlevel
software from the Gill website, www.gillsc.com/support and
connect using an R232 to USB cable (available separately from
Gill Sensors & Controls Ltd).
