Supported Applications
The Dwyer Model F7-LPP is a vertical level float switch designed for simple, cost-effective control of liquid levels within tanks. The series provides monitoring or alarm functions suitable for high current solid-state control systems.
The mechanically rugged polypropylene construction supports use in applications requiring heat and chemical resistance with compatible liquids.
Operating Conditions & Performance
The Model F7-LPP operates within a process temperature range of -4 to 176°F (-20 to 80°C) and withstands pressure limits up to 72.5 psi (5 bar). The unit carries an IP67 enclosure rating.
Electrical performance is rated for 140 VAC/200 VDC at a maximum of 1.2 A. The switch type is SPST, field adjustable between Normally Open or Normally Closed configurations, and is supplied in the NO state. Wetted materials consist of polypropylene for the float and stem, with silicone O-rings.
Physical specifications include an overall length of 300 MM, a stem diameter of Ø24 MM (per dimension table), and a weight of 0.38 oz (11 g). The device is designed for liquids with a specific gravity of 0.8 or higher; the float density is listed as 0.67.
Key Performance Parameters
- Temperature Limits: -4 to 176°F (-20 to 80°C)
- Pressure Limit: 72.5 psi (5 bar)

Configuration Options
The Model F7-LPP series is offered as a single base configuration. The switch action is field adjustable to meet specific control logic needs, allowing the user to configure the output as Normally Open or Normally Closed.
Installation utilizes an M8 thread process connection with an included fastening nut. The electrical interface consists of 24 AWG lead wire extending 11.8" (30 cm) from the housing.
Construction and Materials
- Housing Material: Polypropylene
- Wetted Parts: Float/stem: Polypropylene; O-ring: Silicone
- Dimensions: Overall length 300 MM, stem diameter Ø24 MM (per dimension table), float height 43 MM
Key Product Differences
The Model F7-LPP is a distinct vertical level switch model. No additional configurable options or alternative housing styles are documented for this series in the provided sources.
Important operational notes indicate that mounting near ferromagnetic parts may vary switching distance, and electromagnetic influences can alter sensor behavior. Installation should avoid locations with turbulence from fill pipes or drains to prevent false actuations. The unit is not field serviceable; attempting repair may void the warranty.
