Large Size – Alloys
These units solve the problem of point level sensing in tanks with
inaccessible tops or bottoms, or at intermediate locations in larger
tanks. Operation is positive and dependable. The float pivots with
changing liquid level, displacing a shuttle which magnetically actuates
a hermetically sealed switch within the unit. Installation is through the
tank side at the detection point.
LS-2050 Series – Brass and Buna N
General purpose materials designed to
provide reliable service in oils and water.
