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.

Irrigation is fundamental to the production of food all over the world. Most of us have seen the large center pivot systems used on many farms today, and there are a number of other technologies that are designed to deliver water to crops to allow them to flourish. Less prominent, however, are the systems that collect and deliver water to these irrigation systems to allow for crop growth.
