Marine Liquid Level Sensor | GSlevelM

The Marine liquid level sensor is specifically designed for marine applications where accurate monitoring of fuel or water is required. Using solid-state capacitive technology to sense the level of liquid, Marine Liquid Level Sensor offers high accuracy data and electronic operating temperature range of -40°C to +125°C.

The sensor features an Industry recognised NMEA 2000 compliant output allowing 'plug and play' compatibility with a network of electronic devices.

Manufactured from marine grade 316 stainless steel, the capacitive sensor has no moving parts, floats or other mechanical linkages, providing excellent long-term reliability and freedom from maintenance, to a wide range of marine applications including workboats, large leisure and inshore commercial vessels.

The Marine Liquid Level Sensor features both SAE 5-bolt and 1.25" mounting for easy installation and is available up to 2m long.
