The need for clean, healthy, and safe water is very important in municipal, commercial, and industrial environments. For the most part, there are levels of quality controlling the usage of particular equipment in these environments, providing instruction, and can have the impact of law in several jurisdictions.
Precise and exact control of pumps is vital in potable water applications. The intent or aim is to enhance and boost efficiency with accurate monitoring of water volume over distribution systems. And at the same time, determining possible performance issues.
This goal needs effective flow measurement. For a little help, we will walk you through why accurate flow measurement is quintessential. So, take a read!
Direct Flow Measurement
Direct flow measurement is, more often than not, a critical advancement throughout the industry as it gets rid of mishaps or errors derived from the fluid’s physical properties. In particular, the dissimilarity between the volumetric and mass flow.
Without a doubt, mass isn’t influenced by fluctuating pressure and temperature. For this reason, it is an essential procedure of fluid flow measurement. On the other hand, volumetric flow, with regards to the accuracy and preciseness that the calibration reference conditions and process conditions are attached to, remains valid.
Volumetric flow meters, for example, turbine flow meters and variable area flow meters, cannot distinguish pressure or temperature changes. Moreover, mass flow measurement uses the Coriolis force phenomenon.
Learning Pump Performance
Industrialists who deal with sanitary processes, for example, food and beverage production, and municipal water systems operators, utilize the SDWA pumps complaint. These pumps are designed with nonhazardous materials or stainless steel, which are easy to clean and disassemble.
Precise and exact control of pump systems is a crucial issue in such applications, which are, for the most part, depicted by reduced water consumption and intermittent low flows. Nowadays, water delivery systems present huge pipes with low overall volume capture and low-flow velocities.
The generated flow of the pump is, in nature, volumetric. The accuracy of any flow measurement is extremely dependent on the properties of the fluid. Errors or mishaps in flow metering can be, more often than not, derived from process conditions such as wear of components, air entrapment, pressure variations, and temperature changes.
Data states that the output of the pump flow can differ dramatically because of the system or environmental changes, wear of components, or a mixture of both. Flow rates throughout the pump are calculated for several reasons: to know custody transfer gross billings, to oversee the whole pump performance, to mend corrosion, to treat disinfection, and to measure the losses of the distribution system.
Most characteristics or features of the performance of the pump can be connected or linked with fluid flow. Thus, knowing and learning pump performance entails a fundamental knowledge of related performance curves and specifications.
Selecting A Flow Measurement Technology
Municipal, commercial, and industrial organizations have the option to choose a metering technology for attaining safe water contact and accuracy in pump control applications. A wide selection of electronic and mechanical metering technologies are accessible for any liquid flow measurement.
The most popular and generally used technology are turbine flow meters with components that are stainless steel wetted. Next, are electromagnetic flow meters and both clamp-on and inline ultrasonic flow meters. All of these metering technologies are safe and harmless for use in potable water.
Turbine metering technologies are validated and authenticated flow meter type and affordable solution for small-scale line sizes. They’re well-known for repeatable, wide turndown, and accurate measurements.
This flow meter type generates a large amount of pulse rate output signal that corresponds to the velocity of the fluid and volumetric flow rate. However, keep in mind that turbine meters are bounded to clean fluids and need regular recalibration service.
Furthermore, because most drinkable water processes have conductive liquids, electromagnetic meters are ideal for such tasks. This metering technology aid in meeting measurement accuracy goals, allowing more affordable pump operation. Electromagnetic meters offer diagnostics to bestow improved reliability, reduced costs, and process insight.
On the other hand, a lot of manufacturers choose non-contact ultrasonic flow indicators because they adhere to the NSF protocols and installation without cutting or disturbing the pipe. Moreover, clamp-on ultrasonic meters can be a very helpful tool to manage system performance and pump performance.
This flow meter type can give the load profile info and baseline info prerequisite to reduce costs, energy consumption, and maximize system efficiency.
Good measurement practice and flow meter calibration are crucial and essential to attain repeatable and accurate flow measurement. But choosing the ideal solution is dependent upon learning the performance and uncertainty needed for a certain application, requiring a basic understanding of the pump performance and the application. Getting the appropriate solution has the possibility to deliver huge benefits and advantages through enhanced control and efficiency. There are lots of options to choose from, such as flow meters from smartmeasurement.
