T4000
T4000 Turbine Meters are designed for installation where occasional low and moderate to high sustained flows are demanded. Water passes through the meter without a change in flow direction, driving a helix rotor in direct proportion to the quantity of water passing through the meter. Rotor revolutions are transferred to a register by a magnetic drive.
Gas Meters

200 CFGM
The 200CFGM gas meter is a remarkably small, lightweight meter ideally suited to residential submetering applications. Despite its small size, the meter is incredibly accurate and reliable when measuring either natural or LP gas. The 200CFGM is classified as a 200 cubic foot per hour (cfh) non-temperature compensated gas meter with cyclometer register.

250 Series
The 250 series is a 4 chamber diaphram type gas meter. Its compact size, light weight, long life, high accuracy and maintenance-free operation make it a perfect choice for retrofit or new applications. This meter is ideally suited to light commercial or larger residential use. Meters are equipped with pulse output for interfacing with interval data recorders. The 250 is for use with loads ranging from 200 to 250 CuFt/Hr. These meters can accomodate pipe sizes of 3/4” and 1”. The last digits in the model numbers indicate the pipe size. The meter is shipped complete with a connection kit.

400A Series
The 400A series meters are positive displacement gas measurement devices for loads up to 400 CuFt/hr. These meters use proven diaphragm meter technology in a three chambered design to provide accurate measurement across their flow range. Long life and low maintenance are assured by the combination of a self-lapping orbital valve and a one piece seamless diaphragm.

FM Series
The FM series meters are highly accurate solid state gas meters suited for commercial and industrial gas measurement applications for flow rates from 40 to 56,000 actual CuFt/hour. These
meters use the Fluidic Oscillating Principle and have no moving parts, making them ideal for applications where continuous flow to the customer is required. The lack of moving parts also means
the only associated maintenance requirement is the built-in battery which has a typical operating life of 8-11 years.
Hot Water Meters

H130
The H130 (formerly 5UM-20) is a single-jet (inferential) impeller meter. The impeller movement is transferred by a magnetic coupling to the hermetically vacuum sealed register.

H190

coupling to the vacuumized and hermetically sealed register, which can be turned to any position for easy reading.

H4400
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.
