IMPORTANT:

• Dimensions should be calculated from the top of the tank or riser down to the required alarm level(s) in inches.
• Be sure to take into account any riser pipes or manway risers.

LF-SERIES SENSOR

LIQUID LEVEL FLOAT SENSORS

• Stainless Steel or Brass Mountings
• 1 to 6 Actuation Levels
• Lengths to over 11 feet
• U.L. Recognized, CSA Listed

LF series float sensors have multiple options including material of construction, mountings and float sizes. This allows for the LF sensor to be extremely versatile in a wide range of applications such as water, oils, chemicals and corrosive liquid. LF-* switches are U.L. Approved for Class I, Division 2, Groups A, B, C, D hazardous locations. FM Approved explosion proof junction box must be installed for Class I, Division I, Group D hazardous locations.

Switch actuation levels are determined following the guidelines below:
All units 72″ or less overall unit length with Stainless Steel or Buna N floats.
A = 1-1/2″ (38.1mm) minimum distance to highest level (2″ (50.8mm), Type 5 only)
B = 2″ (50.8mm) minimum distance from end of unit to lowest level
C = 3″ (76.2mm) minimum distance between levels
D = 1/4″ (6.3mm) minimum distance between actuation levels (Note: One float for two levels can be used only when low level is N.C. dry and high level is N.O. dry)

• Actuation level distances and L0 (overall unit length) are measured from inner surfaces of mounting plug or flange
  Length Overall L0 = L1 + Dimension B. See mounting Types for Maximum Length values Notes:**

  1.  A, B and C dimensions based on a liquid specific gravity of 1.0
  2. One float for two levels can be used only when 20VA switch is used
  3. Actuation levels are calibrated on descending fluid level, with water as the calibrating fluid, unless otherwise specified
  4. Tolerance on actuation levels is +/- 1/8″ (3.2mm)

• Units greater than 72″ (1828mm) overall length are supplied with collars with setscrews (made of same material as stem and mounting) in place of float-stop rings. Collars are optional on units less than 72″ (1828mm) overall length. Units requiring 316 SS float stops must be special ordered with 316 SS collars instead of grip rings. In some instances, the use of concentration of chlorine and other corrosive compounds in the media require the use of collar type float stops.
