FOWS 40U AND 50U Brass and Stainless Steel
DESCRIPTION
Fluid Electronics’ Oil/Water Interface Sensors (Single float model FOWS 40U and Dual float model FOWS 50U) provide reliable and accurate monitoring of the oil/water interface level within oil/water separators. The buoyancy design of the floats provides precision monitoring of the oil at either one or two different levels. The single float model and the top float of the dual float model provide a High Oil alarm when the oil should be pumped out of the oil/water separator. The dual float model also provides a High High Oil alarm when the oil level has accumulated to the point that the effluent quality of the oil/water separator may be affected. These sensors are used in conjunction Fluid Electronics’ Control Panels. The Single and Dual Sensors are approximately 18" and 20" long respectively and can be installed in all tank diameters. They are available with either a Brass stem (FOWS 40U - B or FOWS 50U - B) or Stainless Steel stem (FOWS 40U - S or FOWS 50U - S). The sensors are designed for easy and accurate field installation. As an option, the sensors can be installed at the factory before shipment. If installed in a 4" tank opening this sensor may be installed using a 4" x 2" reducing bushing for rigid mounting or it may be installed using an optional extractor fitting installation which allows easy removal of the sensor for inspection and maintenance.

FOWS 500 Brass and Stainless Steel
DESCRIPTION
The FOWS 500 is a Dual Float Oil/Water Interface Sensor that provides reliable and accurate monitoring of the oil/water interface within oil/water separators. Buoyancy design of the dual floats provide precision monitoring of the oil at two different levels: High Oil and Pump Out. This sensor is used in conjunction with Fluid Electronics' CPF Control Panels.
If installed in a 4" tank opening this sensor may be installed using a 4" x 2" reducing bushing for rigid mounting or it may be installed using an optional extractor fitting installation which allows easy removal of the sensor for inspection and maintenance.

FOWS 400 Brass and Stainless Steel
DESCRIPTION
The FOWS 400 is a Single Float Oil/Water Interface Sensor that provides reliable and accurate monitoring of the oil/water interface within oil/water separators. Buoyancy design of the single float provides precision monitoring of the oil at the pump out level only. This sensor is used in conjunction with Fluid Electronics' CPF Control Panels.
If installed in a 4" tank opening this sensor may be installed using a 4" x 2" reducing bushing for rigid mounting or it may be installed using an optional extractor fitting installation which allows easy removal of the sensor for inspection and maintenance.
