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.

Picture this: You’re driving on the highway and push your car’s speed to the limit. Suddenly, a police officer pulls up behind you. Your heart races and stomach drops. You hold your breath as your eyes quickly dash to your car’s speedometer, double-checking your speed. Luckily, you aren’t going over the speed limit. Just as the butterflies in your stomach start to settle, red and blue lights start flashing behind you. You slow the car and come to a stop. The officer tells you that you were going far faster than you thought that you were. Turns out, your speedometer is out of calibration. Now, not only are you running late, but you also owe the state a couple hundred dollars.
If your speedometer isn’t calibrated properly, you risk fines, damage to your vehicle, and endangering those around you. You may face similar consequences if your instrumentation is not calibrated at a regularly established interval. You could be subject to disciplinary action from regulatory bodies, damage to your instrument or surrounding equipment, or even harming building occupants by using equipment that is out of specification.
