Basically, a flow meter is a device that is used to look for the mass or volumetric flow rate of liquids as well as gases moving via a channel. There are numerous forms of flow meters, including mechanical types, like turbine meters and rotary pistons; optical flow meters; and meters that determine fluid using pressure, like cone and venture meters. Each one is created for a specific type of fluid and performance, and therefore, it’s imperative that you examine these factors first before choosing other flow meter qualities.
Together with considering the qualities of the fluids to be processed along with the processing conditions, it’s also important to take note of the technique by which the meter will take its measurements since this can impact the precision of measurements. For instance, a transit time ultrasonic flow meter is considered to be better than Doppler flow meters; even so, it could just be used for “clean” fluids such as water and oils, whereas the latter can be used to determine impure fluids with particles.
Once these technical matters have already been decided, the next factor to consider will be the portability of the flow meter. In processes that require constant and long-term measurement, permanent flow meters are ideal since these will require less adjustment and are therefore not vulnerable to alterations in accuracy. The process of installation for this form of flow meter also varies; they could be set up simply by clamping the device onto the line or by installing them through a hole. Make sure you consider these carefully as the installation method could affect accuracy and simplicity of maintenance.
For companies that only require a measuring device occasionally and for short periods only, like during inspection of HVAC utilities in buildings, the best choice would be portable flow meters. For such purposes, it's always best to choose flow meter hire because this can significantly help save funds for the business.
