1. Product description
The 7010 Liquid Level Sensor is designed for use in harsh environments at extreme operating temperatures
where the continuous real-time liquid level monitoring of a variety of fuels, oils, chemicals, saline, and water
is required. The sensor has no moving parts, oats or mechanical linkages providing excellent long term
reliability.
Liquid level detection is achieved through solid-state capacitive technology. An outer tube and inner rod act
as the plates of a capacitor, with any liquid providing the dielectric between the two. As the liquid level rises
and falls, the capacitance of the sensor changes linearly. The on-board electronics process this and provide an
output as a voltage or current signal.
Calibration of the sensor is achieved by setting a maximum (full) and minimum (empty) level for the desired
liquid. The liquid level between these points is determined by proportionally relating the output to the two
set points, while taking account for the dielectric constant value of the liquid.
If requested, further accuracy can be gained by compensating for the eect of temperature changes on the
output in a given liquid with osets across the temperature range.
Your chosen calibration has passed through Gill Sensors & Controls Limited’s quality control to ensure the
sensor provides market leading measurement accuracy in your specied liquid.
The sensor is designed to operate in uids where deposits or build-up of sediment are not expected, as this
may block the bleed holes unless they are regularly maintained. For uids where deposits or build-up of
sediment are expected, please contact Gill Sensors & Controls Limited for a suitable sensor.

A breakdown of the sensor is provided below with key measurement considerations.
Please contact Gill for any additional information required.
The sensor electronics are housed in the ange, outside the measurement tank. The outer tube is placed into
the measurement tank, such that will be submerged in liquid. The sensor can be installed using either built in
thread or a ve bolt SAE mounting, both providing a tank seal.
2. Getting started
The analogue output cable has seven wires:
The installation of the sensor has dierent requirements, depending on the analogue output:
Voltage
The sensor is provided with a factory calibrated output range of 0.25 V to4.75 V. The sensor can be
congured to a maximum output range of 0.25 V to 10 V.
The power supply must be at least 0.5V greater than the maximum output voltage required. The
switch output requires a pull-up resistor of 1 kOhm to 10 kOhms.
Current
The current output is 4 – 20 mA. The measurement output requires a 250 Ohm load resistor across the
output. The switch output requires a pull-up resistor of 1 kOhm to 10 kOhms.

3.1 Tank proling
The sensor is congured for use with regular tank proles, such as that shown below.
The sensor is supplied so that it reports the level in a linear path as the level rises. However, this will not be
suitable for an irregular shaped tank, such as that shown below.
In this situation, 50% of the tank volume is not half way up the probe. To correct for this tank proling can be
used. This can be done in the GSlevel software and is covered in detail in the GSlevel User Manual.
4. Installation
Do not remove the packaging until you are ready to install the sensor. Prior to installation, please check the
sensor for any signs of transit damage. Contact Gill Sensors & Controls Limited immediately if this is the case.
IMPORTANT DO NOT attempt to cut the sensor to length or bend the sensor. Both actions will result in the
sensor failing and will invalidate the warranty.
IMPORTANT The sensor must not be used in a tank that is not adequately vented.
IMPORTANT The sensor ange and cable must not be immersed in the liquid.
IMPORTANT Diagrams in this section are not to scale and are for reference only.
This manual covers installation of sensors in the conventional manner (see below). For inverted installation
(see below) please contact Gill Sensors & Controls Limited.
All 7010 sensors using the 1.125” UNF or 1.25”BSP tting can be mounted using the SAE 5-bolt pattern using
the supplied gasket. These sensor types can also be tted with the supplied O-ring. The 2” NPT version has a
tapered thread and is sealed as the thread is tightened onto the tank using either PTFE tape or pipe sealant
(not included). Use of an O-ring or gasket is not necessary with this version of the sensor.
The sensor must be installed on a at surface, such that it occupies the deepest part of the tank to be
measured.
The sensor can be installed at any angle from vertical to a maximum recommended angle of 45°. For sensors
over 500 mm in length in dynamic applications, in-tank support of the probe is recommended. Ensure
that the mounting hole in the tank is strong enough to withstand the forces imposed by the sensor from
its weight and the vibrations it may be exposed to. Please contact Gill Sensor & Controls Limited to discuss
specic sensor requirements when mounted at an angle.

Before installation, ensure you have sucient clearance above the tank in to order to mount the sensor. The
sensor is rigid, therefore the clearance height must be, at a minimum, the designated length of the sensor plus
30mm to allow for the ange on sensors with 1.125” UNF or 1.25” BSP ttings. The 2” NPT sensor has a top exit
cable and requires a minimum of 75mm clearance above the top of the tank. Sideways clearance may also be
required, and should be accounted for.
