Mercoid Series 102/1102

Flanged Chamber Type Level Control

Mercoid Series 102/1102 Flanged Chamber Level Control

Operating Pressures to 300 PSIG — Easy Inspection Access

By unique design, you can remove just four bolts from the inspection plate to examine the float and chamber for cleaning or wear without disconnecting the piping or electrical circuitry. The sturdy Series 102 operates at pressures to 400 psi (28 bar) and temperatures to 425°F (218°C). The 102 Series operates to a minimum specific gravity of 0.60; the 1102 Series to 0.40 under the same conditions. Both offer a choice of cast iron, cast steel, or cast 316SS float chamber and are well suited for pressure or vacuum vessels where ease of accessibility is desired.
