General Information

MD-Series meters use the multi-jet principle, which has

been an internationally-accepted standard for many

years. This type of meter is known for its wide range,

simplicity, and accuracy in low-quality water. The

impeller is centered in a ring of jets, with inlet jets on

one level and outlet jets on another. A gear train drives

the register totalizer dials. For pulse output, one of the

dials is replaced by a gear, which turns a magnet that

is detected by an encapsulated sensor threaded into

the outside of the lens. Pulse rate is determined by the

gear and the dial on which the gear is placed.

Mechanically, all MD-Series meters are the same. The

difference between MDE and MDR meters is in the sen-

sor. MDE meters use a solid-state, long-lasting Hall-

effect sensor, which requires power. They are suited

for use with SeaMetrics controls and metering pumps

(LMI for instance) which have sensor power. MDR

meters use a two-wire reed switch. They provide a dry

contact closure and do not require power. MDT meters

do not have a sensor, totalize only.
