The water level probe is a key device that enables accurate monitoring of water levels in reservoirs, wells, rivers, etc. Water level control is important in various applications such as: monitoring of water resources, groundwater level control, management of sewage systems, agricultural irrigation , or in the context of safety (e.g. in the case of flood protection). Water level probes can also be used in alarm systems to report excessive or insufficient water levels. Thanks to them, you can take appropriate actions, such as starting pumps, warning about the risk of flooding or the need to replenish water resources.

A pressure transmitter is a commonly used device that converts the pressure value into an appropriate output signal. The signal from the pressure transmitter is read and forwarded to the control system. In times of shrinking fossil fuel resources, looking for alternative energy sources is a necessity. Hence the increasing popularity of hydrogen, which is the most common element in the Universe and one of the most common elements on Earth. However, not every pressure transmitter can be used to work with hydrogen. Why is it like that? Which sensor technology in the pressure transmitter is best for this medium? We answer these questions below.
