Target flow switches? How to wire the target flow switch

The characteristics of the differential pressure flow switch mainly include: accurate flow control, no additional resistance to the system, no requirement for the diameter of the water pipe and no water flow disturbance interference, etc., it can replace any form of target flow switch as the flow control of HVAC water system.

Differential pressure flow switch is a precise flow control method compared to target flow switch, and it has accurate flow control value. It is installed directly in the unit, avoiding the occurrence of incorrect installation by the user. A common cause, a common struggle, can give people the strength to endure everything.

The difference between the differential pressure flow switch and the target flow switch is mainly in the following two aspects, firstly, compared with the target flow switch, the differential pressure flow switch can avoid the false flow caused by the cavitation of the pump. Therefore, it can be widely used in the water flow control of modular air-cooled heat pump units using brazed plate heat exchangers, casing heat exchangers and shell and tube heat exchangers, and has the function of partial antifreeze protection.

Target flow switch is a kind of flow switch, flow switch has these forms: leaf type (target type), piston type, differential pressure type, float type, electromagnetic type. You can choose according to your characteristics.

Target flowmeter is a kind of resistance flowmeter, it has no switch, can only be through the front and rear valves to the instrument in the air, the meter is through the speed of the fluid through the flow meter generated by the resistance converted into the flow rate to reflect to the central control room.

It is the switch of the flow of the switch, and the switch of the flow rate should be controlled and installed well, and it is easier to open a little, which is still a little simpler.

Aren't all mobile phones now available in mobile phone manager, or security center, there is a traffic control in that, and you can selectively control the traffic in**.

This switch is still very good, and it is more convenient, and it belongs to a new type of switch method.

This passage can be found in the settings, or some sense of his manual to find.

This flow switch is a switch that monitors the flow of water.

It is not difficult to operate on the spot, and it is difficult to explain it here, I hope to understand.

He may have been a little more reliable with the switch a while ago, well, and a little more accurate.

In this case, if you turn on the flow switch of this thing, it will help you control the amount of flow, so it's okay, and if you turn on the switch, you can use it casually.

Dear, hello, I'm glad to answer for you, the wiring method of the target flow switch is as follows:1Confirm that the diameter of the pipe and the diameter of the flow switch match.

2.Install the flow switch on the pipe and secure it using a bracket. 3.

Remove the fittings at both ends of the pipe, and then install the flow switch on the pipe. 4.Connect the two ends of the pipeline with the flow switch, one end of which is connected to the inlet bucket of the flow switch, and the other end is connected to the outlet of the flow switch.

5.Connect the signal line of the switch to the input of the control device (such as PLC, DCS, etc.). 6.

Connect the power cord to the power terminal of the switch. 7.Start the control equipment, and then control the flow switch through the control equipment to realize the measurement and control of the flow rate.

Notes:1Before installation, it is essential to check whether the pipes are clean and ensure that there are no debris or sediment.

2.After installation, testing and calibration are required. Dear, the above is mine, I hope these contents can help you, thank you for your understanding and support, I will continue to work hard.

Thank you, dear.

How it works:

Target (baffle) flow switches are used to detect one-way or two-way flow of air, oil and water, and there should be no entanglement in the medium. When the fluid flows through the pipeline, the baffle is deflected, and the single-pole double-throw micro switch is adjusted to act on the set flow rate by adjusting the adjusting bolt, and the switch signal is output; During the two-way detection, the baffle offset pushes the magnetic module up and drives the switch module to act. It is used to detect one-way flow of air and water, and there should be no entanglement debris in the water.

When the fluid flows through the pipeline in the indicated direction, the baffle is deflected, and the SPDT micro switch is activated on the set flow rate by adjusting the adjustment bolt, and the switching signal is output. The set flow range is large, easy to adjust, and widely used in water, gas, oil and other media measurement.

The wiring principle and diagram of the target flow switch are as follows: 1. Connect to the incoming terminal, and the output terminal is connected to 3 when normally open or 4 when normally closed according to the requirements

For details, please refer to.

The user does not need to install and wire on site, which avoids the inaccurate installation of the target water flow switch and leads to the unit do=newsdetail

Target flow switches, also known as baffle flow switches, can be used to detect one-way or two-way flow of air, water and oil, usually there should be no entanglement in the medium. When the fluid flows through the pipeline, the baffle is deflected, and the single-pole double-throw micro switch is adjusted to act on the set flow rate by adjusting the adjusting bolt, and the switch signal is output; During the two-way detection, the baffle offset pushes the magnetic module upwards and drives the switch module to act, which is used to detect one-way flow of air and water, and there should be no entangled debris in the water.

When the fluid flows through the pipeline in the indicated direction, the baffle is offset, and the single-pole double-throw micro switch is adjusted to act on the set flow rate by adjusting the adjusting bolt, and the switch signal is output.

And the set flow range is large, and the adjustment is convenient and widely used in water, oil, gas and other media.

What is the working principle of the target flow switch.

Target flow switches are generally recommended to be installed at the outlet and inlet; Equivalent to 5 times the diameter of the straight pipe section, in order to ensure the measurement accuracy of better monitoring of the equipment.

The most important thing is to install the right flow direction.

When the fluid rushes towards the blade, the blade oscillates, changing the relative position of the magnet to the reed contactor, excites the contactor to close or disconnect, once the fluid is interrupted, the blade returns to the starting position, and the reed contactor is excited again, the mutual repulsion of the two magnets provides the force required for the flow switch to reset, and the contactor returns to its previous state.

In the structure of the target flow switch, the force required for the blade to recover is replaced by a magnetic switch, so that the flow switch is more stable and durable, and is no longer sensitive to the peak pressure. This target flow switch has the advantages of instant response, low pressure drop, high pressure resistance, and repeat the switch more times, and the on/off depends only on the flow rate, not on or under pressure.

The plug-in target flowmeter is a new type of capacitive force induction flow plug-in target flowmeter developed on the basis of the traditional target flowmeter and with the development of new sensors and microelectronic technology, which has the characteristics of no moving parts of the flowmeter such as orifice plate and vortex street, and has high sensitivity, accuracy comparable to that of the volumetric flowmeter, and wide range.
