Is this Micropilot level sensor not the perfect match for your application?
Micropilot FMR10 is a sensor for continuous level measurement for liquids in storage tanks, open basins, pump shafts and canal systems.
The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method (ToF). It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.

Radar level sensor FMR10 used at BIELMLEK Spółdzielni Mleczarskiej* in Bielsk Podlaski
*BIELMLEK Spółdzielni Mleczarskiej is a dairy cooperative
• Type of liquid: flotation sludge from dairy effluents; 13-15% dry matter.
• Cylindrical underground tank with conical bottom; tank diameter: 6m, depth: 7m.
• Measuring range 5m, temperature 12-15ºC, atmospheric pressure.
Radar level sensor FMR10 at the Koczergi Bio-Power Plant / DMG sp. z o.o.
• Type of liquid: biomass effluent.
• Dimensions of the tank: 5.5 x 11 x 5m
• Measuring range: 4-20mA for 0-100%, tank capacity of about 300m3.
• Temperature: 20-40ºC, atmospheric pressure.
The situation at Bio-Power Plant is reported by Paweł Dziewulski, who works as the Operator of the Biogas Production Line - Automation Technician.
"The Micropilot FMR10 radar [level sensor] was installed in November . According to my observations and my colleagues', who operated the sensor, it is characterized by the simplicity of its two-wire electrical connection. Thanks to Bluetooth communication, we were able to connect with the sensor without any need climb on the tank and we parameterized it according to our needs (the previous device was very inconvenient to set up). The best feature of the radar FMR10 is its fast adaptability to the measured levels and to the requirements of the PLC controller without the need of any interference in the program."
