Float level meters and switches

Float-type level gauges and switches are used to measure and indicate the level of liquids. They provide reliable data for monitoring and automatically controlling pumps and other equipment in tanks, sumps, and industrial facilities.

Float level meters

Float-type level gauges measure the level of liquids using the float principle. They are suitable for precise monitoring in tanks, sumps, and open channels, and provide reliable data for control and monitoring.

PSH-30 - Float-Type Continuous Level Gauge

The PSH-30 measures the liquid level and the temperature of the level sensor, which may, with a certain delay, correspond to the temperature at the measurement point. Thanks to a modern measurement method, the level sensor achieves a resolution of 1 mm over a virtually unlimited measurement range. It allows for measuring level fluctuations over a range of up to 30 m. Only a single cable runs from the sensor, connecting it to the RS485 interface of the H3 unit or to the H1 Hydro Logger.

Float switches

Float switches are used to monitor and control liquid levels. They enable the reliable activation of pumps and alarms in tanks, sumps, and industrial processes.

NIVOFLOAT NL-100, NW-100 - Float-Type Level Switches

The NIVOFLOAT NL-100 series float switches are used to switch on and off at specified levels of both drinking water and wastewater. The double polypropylene housing ensures perfect watertightness, and cable lengths of 5, 10, or 20 m—available in PVC or neoprene—meet even the most demanding requirements. A mercury-free switch is built into the float and operates at a 45° angle. The NW-100 series was developed for extremely demanding applications; it features a robust design and a float volume nearly twice that of the NL series. Thanks to its larger volume, the float performs better in denser liquids. Another advantage of this series is that it functions even without a counterweight.

Level meters for wells, boreholes or retention tanks

Water level sensors for wells, boreholes, and retention basins are used to accurately measure water levels. They enable reliable monitoring and data logging for water management and environmental applications.

Level meters with signaling for tanks and fire trucks

Level gauges with alerts for tankers and fire trucks are used to measure and indicate liquid levels during transport and operation. They enable reliable, real-time monitoring of filling, consumption, and safe vehicle operation.
