Digital Flow Switch Flow Sensor Supply Easy to Operate and Install

Knowledge extension:

Flow switch, principle of flow switch

The flow switch is mainly installed in online or plug-in medium pipelines such as water and oil, used to monitor the water flow in the water supply system At this point, when the water flow rate is higher or lower than a set time point, the device will output an alarm signal to the device, and the system will make corresponding indication actions after receiving the signal, that avoiding or reducing the host's ^ dry burning ^ ^

It streamlined structure design, accurate and stable performance, is applied to flow monitoring in pipelines and cooling and lubrication systems for large, medium, and small equipment For example: generator sets, electric motors, rolling mills, compressors, conveyor systems, etc. It can also be applied to monitoring industrial forces such as oil fields, petroleum refining, chemical engineering, ethanol, pharmaceuticals, metalurgy, power plants, papermaking, food, textiles, light industry, water treatment, industrial welding, etc

Typical characteristics

(1) Streamlined structural design, sturdy

(2) Magnetic coupling measurement system

(3) Install in any direction, vertically or horizontally

(4) Multiple material choices

(5) Wide measurement range

(6) Clear flow display scale, easy to read, point rotation, and graduation scale

Working principle of flow switch

The equipment options a conical measuring tube and a measuring target When the fluid passes along the conical tube, the measuring target products display based on the flow rate The display of the measuring target is balanced under the action of the spring balance force, and transmitted to the indication system through magnetic coupling operation, that achieving flow monitoring and control

Installation and Use

Before installing the flow switch, the inputs, welding slot, Sundries and dirt in the pipeline need to be cleaned first It is recommended to use compressed air for purging and Water of crystallization for flushing Pay attention to the fluid flow direction indicated on the instrument casing, and the shear head indicates the direction of output It is recommended to install a straight pipe section equivalent to 5 times the diameter of the inlet and outlet to ensure measurement accuracy The above is the working principle of the flow switch provided by Shanghai Young Measurement and Control Next, we will introduce the usage method and selection instructions of the flow switch

① Installation environment The on site installation environment mainly refers to measuring the size of the pipe diameter, the length of the straight pipe section, where there is vibration in the pipeline, where there is strong magnetic field interference and high temperature radiation heat around

② Security Prevent accidents from happening For example, when measuring corrosive media, appropriate lining materials should be selected based on the corrosive strength, and exploration proof instruments should be selected for flammable gas environments

③ Energy efficiency The pressure loss before and after the fluid passes through the flow meter, the smaller the pressure loss value, the better the energy saving performance Non contact flow meters such as ultrasonic flow meters, electrical flow meters, and elbow flow meters have no pressure loss

④ Fluid characteristics Fluid characteristics mainly refer to fluid composition, temperature, pressure, visibility, etc. Gradually confirm the selection range based on the actual situation Firstly, based on the composition (liquid, gas, steam, and degree of containment), differential pressure flow meters and vortex flow meters are basically suitable for the above fluids

⑤ Accuracy and economy Generally, flowmeters with correlated stable performance, good reproducibility, long service life, and wide range ratio are conductive to increasing the adjustment of process equipment measurement parameters in the later stage, there reducing investment
