What are the types of fuel level sensors that can be used in back-up power generators?
Point level and continuous level measurement using a float, radar, and capacitive technologies. Monitoring mission critical” fuel levels in back-up generator systems needs to be reliable. Gensets are particularly sensitive to failure issues. Emergency generators are often dormant for long periods of time. They need to be available for emergency action when external power is cut off and immediate. Absolute reliability is needed to keep cell phone towers, businesses, and especially hospitals across the world functioning without interruption. Also, a genset may be the only source of power to keep remote applications operating when it is hard to reach for maintenance staff.
The fuel level sensors used for these critical operations have to function regardless of variations to fuel type or quality. It could be something as simple as refilling a diesel tank with non-standard fluid, or a change to a new fuel brand. For that reason, float switches or float sensors ignore these variances as long as the specific gravity of the liquid doesn't drastically change. Radar will also reliably sense any fuel ignoring vapors and changes in fuel. The capacitive level sensor is a point level sensor that can be used for safety as alarm indication for too low or too high fuel levels.
Solutions for Fuel Level Sensors in Back-up Generators
Continuous Float Fuel Level Sensor
XM/XT-700 Series Continuous Level Transmitter combine the durability of stainless steel or brass construction with a lightweight, compact design for restricted spaces. The XM-700 and XT-700 are ideal for tanks less than 2 feet.
Ultrasonic Continuous Fuel Level Sensor
UCL-510 Ultrasonic Continuous Level Transmitter is a non-contact level sensor with no-moving parts built for general purpose small tank applications and offers switch, controller, and transmitter capabilities in one multi-function transmitter. It is suited for corrosive and dirty applications, is virtually maintenance-free, and reduces tank system hardware.
Point-Level Float Fuel Level Sensor
LS-700 Series Multi-Point Level Switch is a compact unit that features the rugged durability of stainless steel or brass construction in a lightweight package. It is ideal for restricted spaces, including tanks less than 4 feet (1.22 m).
Ultrasonic Point-Level Fuel Level Sensor
The XLS-1 Ultrasonic Level Sensor is Gems' rugged alternative to reed switch level sensors. They are compatible with water, water-based, and hydrocarbon-based liquids. The XLS-1 is an ideal solution for sensing liquid levels in generators, water tanks, radiators, and other harsh industrial applications.
Horizontal Point-Level Float Fuel Level Sensor
Built for durability, our LS-7 Series switches utilize stainless steel or zinc bodies. Ideal for any small tank or vessel destined for a rugged environment.
Capacitive Point-Level Fuel Level Sensor
CAP-300 Series Capacitive Level Sensor is compact, low-maintenance and highly-durable sensor that tolerates coating, can be mounted in any position and is compatible with coolants making it the ideal OEM solution for power generation equipment, off-highway vehicles and generators, as well as food & beverage, medical, rail and HVAC applications. NSF/ANSI 169 compliant models are available for use with water, coffee and dairy.
