If you’re looking to purchase a new water meter, it can be hard to discern what type of meter you should pick. There are many things to consider, from the body material to the outputs to whether any approvals are required. One of the most important considerations for selecting a meter for your application is how the meter will be installed, as certain technologies can limit the meter’s installation orientation. For example, multi-jet meters measure flow by generating multiple jets of water against an impeller in an internal chamber. As the impeller rotates, the flow is totalized on the meter face. In order to meet the stated accuracy, multi-jet meters must be installed horizontally. If a multi-jet meter is installed vertically, the impeller will not rotate correctly and the readings will not meet the stated accuracy specification.

Room pressure monitors are devices that monitor differential pressure between two rooms or areas. Differential pressure is the difference of two pressures being sensed.
There are several applications where it is important to maintain a pressure difference between two rooms. This helps to ensure that there are no contaminants entering or exiting a protected area. In a medical setting, an isolation room requires a pressure differential to make sure that no bacteria, pathogens, or viruses enter (or leave) the isolation room. This protects healthcare professionals, patients, and other guests, and minimizes the spread of germs. Room pressure monitors would also be used in areas such as: pharmaceutical manufacturing, semiconductor manufacturing, clean rooms, research labs, vivariums, and clean manufacturing areas.Continue reading “What Are Room Pressure Monitors and Where Are They Used?”
