Liquid Flow Meters and Switches

The function of a control valve is to regulate the liquids’ flow rate through pipelines in a system. And this achieved by putting a valve in the liquid flow’s path. It typically provides resistance to the liquid flow, where process control restrains the flow and resistance by a signal. This signal is actually borrowed from the sensors in a plant. We must note here that when a manufacturer supplies a control valve, he attaches it to an actuator which utilizes this control signal for activating the ultimate control component.  The various kinds of valves are classified by a connection between the flow rate through a valve and the position of a valve stem. 3 prime kinds of valves depending on the connection between the flow rate and stem position are Equal Percentage, Linear, and Quick Opening. The connection between the stem position at a stable pressure drop and the flow rate through a valve is known as the Inherent Valve features. The connection between the stem position for ...

A flow meter is utilized to measure the amount of liquid or gas that moves through a pipe, or flow rate. The applications of flow measurement are diverse and each industry has its own engineering requirements and constraints. Depending on the industry where a flow meter is used, it may be referred to as flow indicator, flow gauge, liquid meter, etc. however, their function is the same: to measure the rate of flow. Listed below are some of the industries where flow meters are used: Medical Therapy Oxygen Therapy In particular, flow meters are required in oxygen therapy. Various machines are used to administer oxygen. The oxygen first passes via a pressure regulator. This regulator controls the high-pressurized oxygen which is delivered from the cylinder. It administered as low pressure. This lowered pressure is monitored or controlled by a flow meter. This function can be selectable or preset. The flow is measured in liters per minute or lpm. The range for a m...

In industrial work settings, the accurate measure of flow is highly critical. Not only does this define profit or loss, but consumer and worker safety are at stake as well. Flow meters are vital in the precise and accurate measurement of flow rate (mass or volume), i.e. the amount of fluid that passes through a pipe. Flow meters are used in a variety of applications. They measure the mass flow rate or volumetric flow rate. The application will depend on the capacity and type of the flow meter. As a result, each type of flow meter will have its own engineering requirements and constraints. A flow meter will often be referred to by its name. Common examples include flow indicator, flow gauge, liquid meter, etc. This depends upon the industry where it is being used; nevertheless, the function will be the same. There are five essential types of flow meters. Although the list below is by no means exhaustive, it addresses the most well-known types of flow meters used in indus...
