Product Information

Tanktronic® is an advanced electronic tank management system that monitors water levels and temperature. It can also manage and control tank filling.  This user-friendly system, which is quick to install, offers a complete cost-effective solution to water monitoring.

The primary monitoring and control hardware for the Tanktronic system is the Control Unit, which can manage up to 4 x individual tank sensors, 8 x Tanktronic Servo Ceramic Valves and 2 x Tanktronic Control Valves plus additional third party devices.  The unit can manage up to four individual tanks.

The unit operates on a 230V/50Hz single phase supply from a switched fused 3A supply. Tanktronic only requires a single power connection to the Control Unit, while the additional modules do not require a separate supply.  The optional Battery Module can provide back-up power if required.

Tanktronic can control up to 4 x separate tanks. This can be up to 4 x single tanks, 2 x pair of balanced tanks, or 1 x pair of balanced tanks + 1 x single tank.  Adding the S-Module will allow additional Control Valves and third party devices to be added.

A range of options allows Tanktronic to support any design of tank layout. The plug-in modules also give the system enhanced functionality and convenience as required by the user:

Sensor – The Sensor monitors both water pressure and temperature. The unit is provided pre-fitted to a connection box for rapid mounting and electrical wiring.  Available as either a single or twin sensor unit with either 3m or 5m cable.

Repeater Unit – Works as an interface extension to the Control Unit, allowing the user to programme, monitor and control the Tanktronic system remotely from a building facilities management office location. The unit does not require a separate power supply and can be sited 100 metres away from the main Control Unit installed in the tank room.

S-Module – An expansion module that can boost the Tanktronic control capacity. Adding the S-Module will allow an additional 2 x Control Valves to be controlled and extra third party devices to be connected to the Tanktronic system.

Battery Module – Provides back-up power to the mains supply, providing up to two days of normal operation before power is expended. A recommended option if the building application is particularly dependent on the Holiday Schedule function.

Tanktronic Servo Ceramic Valve (SCV) – This compact and intelligent valve is optimised for Tanktronic system applications and provides efficient motorised tank filling. Models are available for pipe sizes ranging from ¾” to 2”.

Tanktronic Control Valve – The Control Valve works with Tanktronic to provide tank filling. This in-line valve is supplied with a flanged fitting suitable for pipe sizes ranging from 2” to 6”.

In addition to the standard Sensor input, the Control Unit features 2 x additional input connection ports. These volt-free contacts permit the fitting of third party devices such as leak detection or an emergency override button.

The Control Unit features 4 x volt-free contact output ports. Two are dedicated to Control Valve operation, while two outputs can be used for a variety of third party devices, including:

  • Additional filling valves
  • Low level alarm
  • Secondary shut-off valve
  • Immersion heater
  • Low level pump cut-out

Product Features
Electronic tank management system to monitor and control water level and temperature
Supports single or multiple tanks, with flexible input and output connectivity to suit specific installation requirements
Each tank can be set with its own operating levels to follow up to 10 schedules: close level, fill delay, alarm levels (high and low) and temperature levels (high and low)
Monitoring of high/low water levels and temperature includes a two-stage alert feature: if the first stage "alert" is not responded to, a second stage "override" can take evasive action
Alarms, Fail-Safe and Holiday schedule functionalities, with switchable mode settings between "Normal", "Holiday" schedules and "Auto" operation
Alarms can be sent to Building Management Systems (BMS)
"Holiday" schedule features enables users to vary stored water tank capacity to meet changing levels of demand at different time periods (e.g. weekends, match days, school holidays)
Intuitive interface with quick-start feature, using a set-up wizard that allows standard set-ups to be configured quickly and easily
Simple menu navigation with key status information displayed (e.g. fault and alarm log data)
WRAS approved (excluding SCV)

Tanktronic® is an advanced electronic management system for cold water storage tanks that monitors water levels and temperature and can also manage and control tank filling.  The system is quick to install and offers a complete cost-effective solution to water monitoring.

The core components of the standard system are the Control Unit with pressure and temperature Sensor. The system can be expanded to meet specific requirements: Servo Ceramic Valves or in-line Control Valves can be connected for tank filling, additional Sensors and an S-Module can be added to cater for multiple tanks and a Battery Module is available to provide back-up power.

For added convenience, an optional Repeater Unit (no extra power supply required) enables remote monitoring from building management office locations and can be sited up to 100m from the main Control Unit.

Product FAQs

We’re here to Help!

How many tanks can I monitor/fill with Tanktronic?

With one Control Unit you can monitor/fill two sensors placed in two separate tanks. Two additional sensors/tanks can be monitored/filled with the addition of each S-Module expansion unit. For example, to use Tanktronic with 4 tanks, you would need one Control Unit and one S-Module unit. To control 5 or 6 tanks, you would need one Control Unit and two subsidiary units.

How do I know if the mains power is off for my Tanktronic system?

If mains power is lost to the Tanktronic Control Unit (and the back-up Battery Module comes into use), the status LED will flash green, until mains power is re-established.

How many Battery Modules should I specify, to provide back-up?

The Battery Module back-up unit is available and only used in the event of mains power being severed from the Control Unit. Only one is required to support the main Control Unit and any number of subsidiary modules.


Is Battery Module back-up required at all times?

No, the system will run from the mains supply without need for the Battery Module back-up.


Do the various units need to be installed level? Is this important?

The units will operate if not perfectly level when installed, but we suggest all effort is made to mount the units to a common level, especially if multiple boxes (Control Unit, S-Modules and back-up Battery Modules) are being mounted together. Avoid any stresses being put upon the supporting tabs and cabling.
