Stainless Steel is a type of metal that is corrosion resistant

Questions & Answers

Normally closed (flow disconnects the circuit) is what I'm looking for. What is the smallest flow that will allow the circuit to be disconnected?

I've only recently put it to the test by running water through it from the garden hose. But even a small trickle of water was enough to close the switch. The flow switch has been well-made. The water flow direction isn't indicated, but it must enter through the cone at one end. From China, the delivery took only two weeks.

Is the size of the threads 1/2" NPT?

Hello Marc,br>We checked the product condition with the supplier and discovered that this is not a 1/2" NPT. We apologize for the inconvenience. br>We're working on a new version of the advertisement. It could take up to two days for the updated content to appear.

Will this work if I connect it to a 120v water pump?

This acts as a switch, opening the circuit when the water isn't flowing, but it's not designed to handle high current loads. If you need to power a pump, a contactor or relay should be used. In order to prevent the pump from turning on and off unexpectedly due to changes in the water flow switch, you'll also need a small control circuit. Other "Plug and Play" options for powering a pump if water flows through it are available on the market.

Is it possible to use compressed air in conjunction with this switch?

The water friction activates the flow Switch, which is a spring-loaded and calibrated internal element. Because air has less friction, it can activate at much higher flow rates. It is only suggested for use with water or something similar.

Non- When using with NPT, standard threads leak

3/5

The switch became stuck in the on position, and the boiler ran for the entire night. The sensor has become unresponsive. When the hot water is turned on, the water flows through the sensor, which activates the boiler. When the faucet is turned off, the sensor becomes stuck, and the boiler continues to operate. It was also very difficult to pipe this in because it was dangerous. br>There are a few Q's in the listing. The item does not taper, and the supplier even states as much, and the threads are straight the whole way through. br>I need to purchase this: Due to the leaks and the stuck switch, it had to be removed. br>Can they send me a new one with no stuck switches? br>The new one should have the national pipe thread taper (NPT)br>I also notice rust on the inside. Isn't this supposed to be stainless steel to prevent rust?br>It was all nice and shiny! There was no rust on it, and it appeared to be made of stainless steel. I can't believe it's starting to rust! What are the components of high quality?

The 'ON' condition is maintained

3/5

When used to control a tankless, instantaneous water heater, the unit I received would occasionally stick in the 'on' position, which is unacceptable (and potentially dangerous). I believe that the stainless steel body, which should be very low or non-reflective in theory, is a good choice. The reed contacts stick in the 'on' position because they are ferromagnetic and retain some residual magnetism. I eventually found a unit on Amazon that is described as a "white plastic shell magnetic water flow switch," and it has been working perfectly for over a year. It appears to have the same internal components as the first unit, but it does not have the stainless steel body. Furthermore, it is less expensive.

Quick delivery and a good product, but there were too many limitations for my needs

4/5

I'm a person with a low IQ. For my application, there isn't enough flow through the switch, but the switch worked (it indicated whether or not there was flow). There were simply insufficient details to determine whether or not it would function. On a higher pressure setting (perhaps greater than 10 psi? ), If you don't require a lot of flow in your application, it might be sufficient.

Threads have begun to unravel! I can't get it to seal because the threads aren't half-inch national pipe thread

Sensor for precision

5/5

I like it, and it's working well.

Three out of five stars

3/5

The reed switch needed a lot of water to turn on, so it didn't work well with my tankless water heater.

Stuck on, with a bad thread form

3/5

The unit I received would not toggle and was stuck in the On position. In addition, the threads were either too large or not tapered, and they didn't fit well with NPT fittings. I returned it and will seek out a more suitable replacement elsewhere.
