Chemical plant operators always rely on the plant air pressures for the proper sustenance of the mechanical devices and equipment. One of the customary dilemmas affecting the production plants using the compressed air systems is the ability to maintain dependable air pressure throughout the distribution system. In this context, it is vital to track the precise pressure of the liquids and gases in the chemical plant, wherein the flow switch is a typical mechanical device that ensures such tracking.

Thus, a flow switch or flow sensor, or indicator is a unique gadget that helps in monitoring the flow rate and accurate pressure of liquids, or gases through a conduit system. These metering flow switches are precisely modeled with adjustable set-points for generating and breaking the electric current in a circuit board. The device determines the level of flow of liquid or gas and modifies the set-point according to the specific process requirements. Hence, it is vital to order such precision-guided devices of flow switches and meters from the authentic industrial device suppliers of Gordy’s Sensors. 

What Is Meant By A Flow Meter And Switch?

Flow meters are unique devices that are used to measure linear, nonlinear, volumetric or mass flow rates of liquids or gases. When selecting a flow meter, it is vital to assess the factors of the availability of spare parts, familiarity of the chemical plant workers with such devices, and their expertise in the calibration and maintenance of such devices. As there are no standard or off-the-shelf-flow flow meters that are appropriate for all applications, it is vital to choose the suitable device that covers the features and usage of each type of meter.

The flow switch, also known as the flow indicator or sensor is a mechanical device applied to monitor the flow rate and pressure of liquids, or gases via a conduit system. In most functional scenarios, such devices trigger actions, wherein they can start or stop other components such as the pumps. These functions help it to modify the flow rate and pressure to the desirable and programmed levels.

How Does The Flow Switch Function?

The flow switches are capable to track, report, and control the flow rate of liquid or gas via a particular system part, or through the entire system, assuring that the flow is staying within the pre-set parameters. In this context, the magnetic trigger or paddle is linked to a circuit and positioned in the channel through which the gas or liquid is flowing. This specific trigger device is rotated through the particular substance flowing through it, therein sending a signal that reads back to a secondary component, called the transducer. 

Subsequently, the transducer obtains this raw signal from the magnetic trigger device, passing it to a transmitter in a legible format. In the process, the transducer measures such reading justifying a predetermined set of guidelines. Again, in scenarios, when the rate of flow falls below or exceeds the required level, it can promptly trigger a sequence of actions, like starting the pump, triggering an alarm, shutting down parts, or diverting the flow of liquid or gas. 

Some of the commonly used flow switches are paddle flow switches, variable area flow monitors, calorimetric flow switches, velocity ultrasonic flow switches, and mass flow rate sensors. Most of these flow meters and switches do not have any moving components that are exposed to continuous abrasions, hence they guarantee accurate measurements. 

What Needs To Be Ascertained Before Installing A Flow Switch?

Flow switches can be installed on a straight section of the duct or pipe, wherein it should be ensured that the front and back length of the switch is appropriate. Nevertheless, before inducting such flow switches, it is always rational to justify the type of switch to be used, and its underlying functions. In this context, the industrial users need to avoid fixing or wiring the flow switch near the bends, drains, valves, or the wider or smaller sections of the pipe. Thus, the users also require ascertaining the specific measuring medium, i.e. liquid or gas for which the flow meter or switch is to be used before installing and testing this device.
