Supported Applications
The Dwyer F7-MLK2 Multi-Level Switch Kit provides the components necessary for designing and fabricating a customizable 1 or 2 station level switch. The series is constructed of 316 SS, making it suitable for chemicals, corrosive liquids, oils, and high-pressure applications involving compatible liquids.
Operating Conditions & Performance
The F7-MLK2 operates within a process temperature range of -40 to 275°F (-40 to 135°C) with pressure limits up to 750 psi (52 bar). The switch mechanism is rated for liquids with a minimum specific gravity of 0.75 and supports mounting orientations up to 30° angle from vertical.
Electrical performance includes an SPST output selectable as Normally Open (NO) or Normally Closed (NC), with electrical ratings of 20 VA: 0.8A @ 240 VAC, 0.17A @ 120 VAC, and 0.3A @ 30 VDC.
Configuration Options
The kit allows users to customize the stem length (maximum 36"), actuation points, distance between floats, and lead wire lengths during fabrication. The F7-MLK2 includes two level stations with floats (switch, tube, and float) along with necessary assembly components.
- Wetted Materials: Float/Stem constructed of 316 SS
- Process Connection: 2" male NPT pipe plug
- Tube Dimensions: 1/2" OD tube diameter with a maximum stem length of 36" (91 cm)
- Included Components: Two level stations, two extension tubes (10" / 254 mm), three tube unions, one tube connector, one end fitting, and one mounting plug
- Electrical Connections: 18 AWG x 60" (152 cm) wire leads
- Weight: 3.3 lb (1.6 kg)
Key Product Differences
The F7-MLK2 is a single model kit designed for custom assembly rather than pre-configured variants. The primary variation capability lies in the user-defined configuration of stem length and float spacing within the documented maximums.
