9402 GWR II – Furneco

ROCHESTER 9402 GWR II GUIDED WAVE RADAR | INDUSTRIAL LIQUID LEVEL SENSOR

The 9402 GWR II series represents the next generation of radar sensing, offering significant technical advantages over traditional reed switch probes. It features a robust, low-profile head design (extending less than 1″ above the tank) and a stainless steel waveguide. Because it guides microwave pulses along a probe, the sensor is unphased by variations in liquid properties, agitated surfaces, or foam, making it compatible with diverse fuels including diesel, biodiesel, HVO, and synthetic oils without requiring recalibration.

PRODUCT USES:

Fuel Monitoring: Ideal for remote backup generators and bulk fuel tanks (specifically those over 1,200 gallons).
Industrial Process Control: Reliable measurement in stationary storage tanks for coolants, water, and mildly corrosive media.
Energy Infrastructure: Level tracking at EV stations and remote stationary storage applications.
Constraint Environments: Designed for tanks with pre-existing small access ports or limited vertical clearance due to its side cable exit.
