TC-Series Level Based Pump or Valve Control

Electronic Pump Controller

Single/Twin Tank Level Controller


The 3P TC Series Tank Controller maintains and monitors the level of water in a storage tank. A precise level sensing probe detects the exact height of water present in the tank. The electronic Controller then uses any of four mains voltage outputs which can be connected to pumps, solenoids, motorised valves or any other type of filling or draining device to maintain the level between defined limits.

Each pump or valve connected to the Controller is assigned high and low switch levels, and configured to drain or fill the tank. Additionally, each output can be linked to any of 5 switch inputs, which must be closed for the output to operate. This is in addition to the minimum and maximum levels that the output must operate within and is useful in cases where water is to be transferred from point to point. Filling a tanker for example could be conditional on sufficient water in the main supply tank, and also depend on a shut-off or level switch on the tanker or filling hose. Alternatively a pumped stormwater attenuation system could be linked to a rain sensor to stop emptying the tank when rainfall is detected.

Level sensing is achieved via a single pressure sensor installed on the base of the tank. This reads the actual water depth and the Control Panel then shows the exact level and operates accordingly, thereby removing the reliability issues associated with float switch based systems.

All level settings are set from the Control Panel. There is no need to enter the tank to fit and adjust float switches. High and low level alarms are also set from the control panel, and a switched BMS output (volt free contact) is provided, which can be also used to activate sirens/strobes.

Advanced Fault Tracking detects and logs faults in memory until you choose to erase them, allowing easy identification of intermittent and historical faults.

Overvoltage and brownout protection, immediate recovery from power failures with no loss of setting and auto reboot, individually fused outputs, oversized power supply to electronics, removable MCU chip (software) for easy upgrades. Modular connector design and tolerant software allows pumps and sensors to be ‘hot-swapped’ without switching off the controller or remaining pump.

OEM Solutions

Usually supplied either as a panel and level sensor only, but can be offered to OEM customers as a package, comprising of the panel, pumps, cables, solenoids, hose kits, etc. We work with our customers to provide specific product bundles, with panel and software branded to your requirements.

We provide full training, design and technical support, and will customise the product and accessories to your requirements, and full UK based support and spare parts availability.



  • Excellent configurability whilst retaining an intuitive menu driven user interface.Made in Britain. Designed, built and programmed entirely in the UK by 3P Technik.
  • Full UK support , with customisations to hardware and software available with very short lead times.
  • Modular design allows extremely rapid swap-out of parts. Including hot-swap of connected accessories and sensors (no power-off).
  • Very low lead times. All spare parts stocked by us in the UK for immediate dispatch. We don’t follow the ‘buy to order’ business model of continental manufacturers whose lead times are often unsuitable for UK clients.
  • We can supply not only the control equipment, but also pumps, filtration and all tank fittings.
