Product catalog summary
General Characteristics
The Linear Level Meter offers measuring accuracy options of 5, 10, or 20 mm. It provides various output signals including potentiometric (LC), 4-20mA analog (LCT), and display plus (0)4-20mA analog (LCO). The device can measure up to 6 meters in length and is available in materials such as Brass, AISI-316, PVC, Polypropylene, and PVDF. It can withstand a maximum working pressure of up to 40 Bar, depending on the float type, and operates within a temperature range of -30°C to +55°C with a relative humidity of 90%. The standard working temperature is 105°C, with constructions available up to 150°C upon request. The device is rated with an IP65 protection class.
Floats
Various float types are available, each with specific dimensions, materials, specific gravity, measuring accuracy, maximum pressure, and temperature limits. For example, the B20 float is made of Butadiene Acrylonitrile Copolymer with a specific gravity of 0.55 and can handle up to 20 Bar pressure at a maximum temperature of 105°C.
Electrical Outlets
The device supports multiple electrical outlet configurations, including IP65 housing with DIN 43650 plugs and cable glands in different materials and protection ratings (IP68, IP67, IP54). The temperature class varies with the type of output signal.
Working Principle
The level meter operates on a potentiometric system where a reed-resistance chain is actuated by a magnetic float. This chain is sealed within the measuring stem, ensuring reliability and maintenance-free operation.
Process Connections
The device supports various process connections, including mounting from inside or outside with available threads and flanges. Different float types are compatible with specific connection types and materials.
Electrical Wiring
Wiring configurations are available for potentiometric output (LC), 4-20 mA output (LCT), and display plus 4-20 mA output (LCO).
Dimensions
Dimensions are specified from the fixing point of the process connection, with a tolerance of +3 mm. Minimum distances for various float types are provided.
Nomenclature
The nomenclature section explains the coding system for specifying the device configuration, including output type, float type, measuring accuracy, length, material, process connection, and electrical outlet.

LEVEL METER GENERAL CHARACTERISTICS The working principle is based on potentiometric system, where a reed-resistance chain is driven by a magnetic float. The reed-resistance chain is fully protected and sealed inside the measuring stem; the only moving part is the float.
