Suresite Gems sensors magnetic visual level indicators
Stock No:
Manufacturer
The Gems SureSite® is a magnetic visual liquid level indicator that provides continuous, highly visible tank level indication without requiring electrical power. It is designed as a safe, maintenance-free alternative to traditional glass sight gauges, with the process liquid fully contained inside a pressure-tight housing while a magnetic float actuates an external column of coloured indicator flags
Continuous visual level indication without external power
Magnetic float operation — the internal float tracks the liquid level and actuates the external indicator flags
High-visibility coloured flags provide easy level reading, even from a distance
Pressure-tight construction keeps the process liquid contained
No glass to break, providing a safer alternative to conventional sight glasses
Shock and vibration resistant magnetic flag assembly
Wide range of construction materials, including 316 stainless steel, alloy, PVC, CPVC, PVDF and Hastelloy
High-temperature versions available up to 399°C (750°F)
High-pressure versions available up to 290 bar (4,200 psi), depending on configuration
Long measuring lengths available for large tanks and vessels
Suitable for different liquid specific gravities, with the float selected according to the application
No continuous calibration required
Low maintenance with no electrical power required for basic visual indication
Optional level switches can be added for point-level alarms or control
Optional 4–20 mA continuous transmitters available for remote level monitoring
Suitable for high-temperature, high-pressure and demanding industrial applications.
TTHPLI Trantech high pressure visual level indicator , alloy construction
The Trantech TTHPLI Visual Level Indicator is a simple, reliable and cost-effective solution for direct visual indication of liquid level in atmospheric storage tanks. It provides a continuous visual display of the liquid level using the communicating vessels principle, allowing operators to instantly determine the tank contents without requiring electrical power. The TTHPLI is ideal for water, diesel, oils and other compatible liquids in industrial, agricultural and municipal applications.
