Hot water meter
Product Information
For monitoring hot water flows for batch or continuous flow processes, Elster AMCO Water provides five models of inferential meters to accommodate a variety of flow rates, pipe sizes and maximum temperatures. At the lowest flow rates (¼ to 22 gpm) and pipe diameter (¾”) is the model S130 inferential meter, of the single jet design. Model M150, a multi-jet design meter, is available in sizes 1 and 1 ½” NPT inlet and outlet, for flows from 1/3 to 31 gpm and 7/8 to 88 gpm, respectively. Both the S130 and S150 are brass case meters suitable for measuring water up to 195º F and services up to 150 psi, and both can be equipped to provide dry contact reed switch output of 1 contact per gallon (or per 10 liters). Brass case/brass top plate model M190, multi-jet inferential meters are provided in sizes 1 and 1 ½”, for flows from ½ to 31 gpm and 7/8 to 88 gpm, respectively, in services with pressure up to 230 psi and 266º F. An externally powered pulser insert is available to provide a dry contact reed switch output of 1 contact per gallon (or per 10 liters). Model H4300 is a Woltman design horizontal impeller, with only two moving parts, the impeller and magnet. The H4300, in sizes 2” to 6” that operate with low flow accuracy ± 3% and accuracy ± 1% up to peak flow, is recommended for measurement up to 250º F and pressure up to 230 psi. Either a reed switch element or opto-electronic pulse transmitter can be selected for the H4300. Model H4400, can be installed in services where water temperature can reach 350º F and pressures are up to 195 psi, 250 º F where pressure reaches 230 psi. Available in sizes 2”, 3” and 4” model H4400 offers improved low flow performance ± 2%. Two externally powered pulser models are available for the H4400, a reed switch pulser for output of 1 contact per 10 gallons or per 100 USG and an inductive (Namur) pulser for higher resolution, 3.785 contacts per 1 USG.
