FHRB 810 DUAL-FLOAT-SENSOR
DESCRIPTION
The FHRB 810 is a dual float sensor that is designed for monitoring Hydrostatic Reservoirs of double-wall fiberglass tanks. This assembly is designed to operate in brine solution. It is installed in the reservoir at the top of the tank and consists of two floats, on a stem, with two predetermined set points. If the brine level within the reservoir changes beyond the two set points-(high and low), an alarm will sound at the control panel. The FHRB 810 sensor interfaces with Fluid Electronics' family of Control Panels or with most control panels, manufactured by other vendors.

FLOAT SWITCH MODEL FDAS 710
DESCRIPTION
The FDAS 710 is a float switch sensor that is specifically designed to monitor for the presence of liquid within the "dry" annular space (DAS) of a double-wall fiberglass tank. The sensor can not distinguish between water or hydrocarbon. The switch can be factory installed or field installed. It must be installed in a "Horizontal" position in the annular space. It consists of a single float switch that actuates in the presence of 1/8" of liquid. The FDAS 710 sensor interfaces with Fluid Electronics' family of control panels or with most control panels manufactured by other vendors.

FCBS 700 VERTICAL-FLOAT-SWITCH
DESCRIPTION
The FCBS 700 provides a float switch sensor that is designed to monitor for the presence of liquid within a normally "dry" environment. The sensor can not distinguish between water or hydrocarbon. It must be installed in the "vertical" position in containment collars of fiberglass tanks, bulkhead spaces, interstitial monitoring tubes, oil pans and piping sumps. It consists of a single float, on a stem, and actuates in the presence of 1/2" of liquid. The FCBS 700 sensor interfaces with Fluid Electronics' family of control panels or with most control panels manufactured by other vendors.
