Mueller Systems was founded in 1859 as Hawes and Hersey Company in Boston, Massachusetts and was a manufacturer of bolts, rotary pumps, and other machinery. [3] [4] In 1885, the company received a patent on the rotary displacement meter and began manufacturing water meters under the name Hersey Meter Company, offering its first rotary and disc meters for sale in 1886.
A WMBUS Gateway (Wireless M-Bus Gateway) is a communication device that enables remote reading of water meters by bridging the gap between the water meters equipped with Wireless M-Bus communication modules and centralized data collection systems. The gateway typically operates on standard frequencies such as 868 MHz (Europe) or other ISM bands ...
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...

The general design of the flume detailed in ASTM D5390: Standard Test Method for Open-Channel Flow Measurement of Water with Palmer-Bowlus Flumes. [2] It is important to note that unlike the Parshall flume , the standard for the flume does not set out specific sizes and flow rates, but only general characteristics for the class of flume.
Figure (1) showing typical velocity flow profile for natural gas measurement. The most commonly used description of flow conditions within the pipe is the flow velocity profile. Fig.(1) shows the typical flow velocity profile for natural gas measurement. [4] The shape of the flow velocity profile is given by the following equation,
The meter communicates to its collection point using 900 MHz mesh network topology. Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and ...
