A flow meter is an instrument that is used to gauge the flow rate or the amount of a liquid or gas flowing through a channel. You can see various kinds of flow meters, and these include mechanical flow meters, such as rotary pistons and gear meters; pressure-based meters like the venture and cone meters; and optical flow meters. One popularly used kind of flow meter is the ultrasonic flowmeter. Ultrasonic flow meters can be utilized in building services to keep track of the flow of utilities like water, or in mining to determine the flow of lubricants, water and sludge or slurries used in the mining process.
The first aspect that should be considered when selecting ultrasonic flow meters is the type of meter to be utilized, as well as how the flow rate will be calculated. There are generally 2 different types of ultrasonic flow meters, the first of which is the transit time type. The transit time ultrasonic flow meter measures flow rate by figuring out the difference in transit time of ultrasonic pulses that are transmitted into and against the flow of the substance being assessed. This type of meter has a huge consistency and is more effective at measuring flow rate of substances with little debris, such as water, sea water, sewage and oils.

Another type of ultrasonic flow meter is the Doppler flow meter, which measures flow rate by determining Doppler shift in the material. This type of meter is considered to be less accurate than transit time flow meters; still, it can be utilized for substances that have a greater quantity of particles in it.
In addition to choosing a flow rate meter depending on type and way of measurement, another point that must be considered is whether the meter should be mounted to the wall (or the line) or held by hand instead. Handheld flow meters are more favorable for applications that require measurements in various areas for just a short period of time, such as flow surveys or monitoring of heat, ventilation and air conditioning utilities in buildings. Groups and individuals who only need to use flow meters periodically can likewise opt for flow meter hire as opposed to buying meters. On the other hand, for long-term measurement and monitoring, mounted meters are a better solution.
The final consideration in acquiring ultrasonic flow meters is the type of installation. All these flow meters can be installed two ways, and the first one is by just clamping it on to the line to be assessed. Clamp-on meters are non-intrusive and they are a lot easier to install or maintain. On the other hand, the second type of installation, wetted flow meters, needs drilling into the pipe or installation in line with the pipe. Wetted flow meters are more precise than clamp-on kinds, however they may turn out to be more bothersome in terms of repair and maintenance.
