The Series WMT2 Multi-Jet Water Meter with Pulsed Output is a series of mechanical, water totalizing meters that display the total water usage in gallons or m³ and provide a reed switch output proportional to flow rate. They are available in a range of body sizes and include NPT or BSPT couplings. Not for potable water use, brass contains lead in excess of low lead limits.

Mechanical Water Meters: Available from ¼” up to 6” bore to handle flow rates from a few litres per hour up to 600 m3/hr. Usually used where high accuracy 

Drawbacks or disadvantages of Mechanical Water Meter. Following are the drawbacks or disadvantages of Mechanical Water Meter: Mechanical parts get damaged which requires frequent accuracy testing. It is prone to wear due to silty water. This results into loss of accuracy which requires frequent need for replacement. It has shorter service life.

Description: -free plum as defined by California, Vermont, Maryland and Louisiana state laws and the U.S. Safe Drinking Water Act that took effect January, 2014.Water flows through the meter’s strainer and into the measuring chamber where it drives the impeller. The impeller drives the Liquid Volumetric Flow Rate: 1 to 160 GPM; Electrical Output: Switch

In addition, lists of approved materials for water distribution and wastewater collection systems are included in this document. Unless otherwise specified in the project plans and/or specifications, these materials can be considered by the Contractor contingent upon approval by the Owner. PREFACE P - 1

They can meter flow rates from 1 gpm to 65 gpm in continuous service with intermittent excursions to 100 gpm. Meters are sized so that pressure drop is below 35 psid at maximum flow rate. Accuracy ranges from ±0.5 % AR for viscous fluids to ±2% AR for nonviscous applications. Upper limit on viscosity is 10,000 centipoise.
