Series QMO/QMB

Depth and Level Transmitter

QM model, the highest precise pneumatic level transmittr, is waterproof up to a depth of 350m and uses the polyurethane vented cable being used in seawater and performing atmospheric compensation. I is appropriate for deep wells and tank level. Depending on the embeded place of an amp. this QM model has both QMO(External amp.) and QMB(Internal amp.). Refer to the dimension.
