Flow gauges are instruments used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or gas. Before choosing flow gauges you need to have a clear understanding of the requirements of your particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and the overall installation conditions. When selecting flow gauges, determine if the flow rate information needs to be continuous or totalized, and whether this information is needed locally or remotely. If remote monitoring is needed, should the transmission be analog, digital, or shared? If shared, what is the required minimum data-update frequency ? Other factors need to be also taken into account when choosing flow gauges. For example the fluid and its flow characteristics are critical. The fluid pressure, temperature, allowable pressure drop, density, conductivity, viscosity, vapor pressure at maximum operating temperatures, toxicity, safety of fluid, abrasiveness of fluid, bubble content, ease of cleaning and sanitaton, possibility of slug formation, possibility of pulsation in flow.....etc. need to be considered when selecting flow gauges. Piping and installation conditions are also of utmost importance.
Before purchasing flow gauges, buyers should also make a preference for either mass or volumetric units. For example, when measuring flow of compressible materials, using volumetric flow gauges does not make much sense. Our flow gauges are accurate and have outstanding repeatability specifications.
