Liquid Flow Meters and Switches

In today’s economic environment, energy usage has become a huge concern, particularly on energy efficiency and using flow meters to guarantee accuracy in energy measurement. The upsurge in energy usage demands industries and end users to measure energy usage as accurately as possible. In chilled and heated water applications, the installation of a temperature and flow-measuring device is required. Linked to a BTU computer, the data enables end users to determine how energy is being used, where and how it is used and take steps towards improvement accordingly. However, there are certain limiting factors, which can affect the accuracy of flow meter systems. The following is a discussion on various technologies that can be used to improve flow meter accuracy: Temperature Sensory Accuracy Let us take an application from matched-pair temperature-sensing technology. It is accurate to (+/-) 0.01% of span (0.02 F). The accuracy of both sensors combined is around 0.04...

Through placing a valve in the liquid flow’s path, control valves regulate the liquids’ flow rate through pipelines in a system. This valve typically provides resistance to the liquid flow, where process control restrains the flow and resistance by a signal borrowed from sensors in a plant. We must note here that when a manufacturer supplies a control valve, it must then be attached to an actuator which utilizes this control signal for activating the ultimate control component. Control Valve Classifications Control valves contain two primary parts – the body and the stem . The body incorporates the housing characteristic which brings in the supply line and the delivery line for joining together. The stem incorporates the plug and the valve stem and seat. Transformation in the valve, functioned by the stem, takes place to begin the resistance of flow. The plug and the stem shift in the upward direction, causing elimination in the size of the opening place between th...
