Return
to Water Meters
The H4400 is a Woltman vertical
impeller (inferential) meter. The impeller, shaft and
magnet are the only moving parts in the measuring
element. The magnetic coupling transfers the
impeller movement to an o-ring sealed register.
The meter is for use with hot water
up to 350°F (180°C) with working pressure to 195 psi
(13.4 bar) or 250°F (120°C) with working pressure to
230 psi (16 bar). Both the pressure loss and accuracy
tests are made before shipment. No adjustments
need be made before installation.
The meter consists of a main case, a
measuring chamber, an impeller, a removable top
plate and o-ring with a magnetically driven register
or register with reed switch or opto-electronic pulser.
