To ensure cooling is managed properly, the flow of water may need to be monitored. Compound meters are designed to meet situations with highly variable needs, such as fluctuations in high flowrates and low rates of flow, but where accuracy is required in all circumstances. This kind of meter measures the heat content in water. Many meters are used to calculate monthly water bills, others to measure just the right amount of liquid to add to a product or process. Susette Horspool (author) from Pasadena CA on October 31, 2012: Thanks billybuc and Om. The velocity of turbine is proportional to the velocity of water flowing through it and generates voltage pulse which is a measure of the flow rate. Above: wet areas in the street and a sound of running water led to discovery of a leak outside of the home whose blue PEX incoming water line can be seen connected to the white water main. This is the first I wrote of three hubs on water-related meters, and I learned new stuff with each one. As the technology improves, the acceptance of ultrasonic water metering is growing, usually these meter also come equipped with M-Bus communications which make them controllable and reliable. This kind of meter is how water suppliers measure the amount of water their customers use during the month. Editor's note: 2022/02/04 We sent a request for product specification and technical review of this article to Itron and will report the company's advice here. Turbine meters are generally available for 1- to 12 or higher pipe sizes. Either approach tends to be highly accurate, and they can provide for substantial flow measurement ranges. There is no need for access to the inside of the home. You probably noticed that I'm a geek too.
