The Waste2O bio-digester is a safe and environmentally friendly food waste management system. Designed and manufactured by Mechline Developments, it can process up to 180kg of soft, organic food waste and in 24 hours reduce it to wastewater that is completely suitable for disposal using normal drains and sewers. To ensure the correct fill level of the automatic machine, Mechline uses a Measurement Specialities LS403 series horizontal side-entry level sensor supplied by Variohm Eurosensor.

As an in-vessel bio-digester, the Waste2O uses a powerful biological formulation to digest soft, organic food waste, leaving nothing but wastewater that gets sent to drain. In this way, it helps businesses to divert food waste from landfills.

Variohm’s line of liquid level sensors covers a choice of installation configurations for float and broken finger types in various materials and temperature ratings to 130ºC. Top-, bottom- and side-entry versions are available to suit use in water, chemicals, fuels, oils and organic solvents.

Many models include UL and WRAS (Water Regulations Advisory Scheme, UK) approvals. Switching of simple on/off output with SPST and SPDT contact forms covers typical AC and DC voltage ranges with switching power up to 70W.

Key benefits of product application

  • Mechline required that the Waste2O needed to pass the rigorous safety requirements of TÜV and Intertek product testing for European and US standards. Thanks in part to the LS403 series level sensor, the machine is the first appliance of its kind to gain both WRc and WRAS approval.
  • Peter Sage-Passant, Mechline’s managing director and head of product development, said: ‘It’s an important part of Mechline’s Waste2O food waste bio-digester for the machine to ensure the correct fill level at all times. Without it, we would not be able to provide a critical function to the end user that makes our machine an operationally easy piece of equipment.’
  • Sage-Passant added: ‘Our objective to be best in class would not be achievable without supplier partners like Variohm Eurosensor.’
