Review on 💡 Highly Efficient DIGITEN FS C02 Brass Switch for 0-220V Power Control by Larry Blanco

This product is advertised as BSP. There are two types of BSP. BSPT - Taper & BSPP - Parallel is what it should be. This means that the diameter at the very beginning is exactly the same as the diameter at the end. Unlike National Pipe Thread, which has a cone, BSPP does not. This can still be solved with an NPT adapter and washer and/or pipe tape/joint sealant (as specified in the product description). The problem is that the threads on the one I received were not cut with a BSPP die at a 55 degree angle See attached picture. There is no corner on the thread. A female NPT adapter should thread onto a male BSPP thread with no problem - it just doesn't seal well even 1 thread because the threads are square and not angled. Maybe I got a bad one - as others have pointed out, success with teflon tape. As for the GOODS. This product should be exactly what I need .It works pretty smoothly. There is a piston (the object on the right in the second photo) that is next to the inlet end of the tube. If even a small amount of water flows, this piston slides towards the outlet. external m The installed sensor can catch this magnet through the brass and close the circuit. This is NOT a Hall Effect Flow Meter. Just a magnet moving in the tube. The beauty of the design, however, is that the brass body is not penetrated. The magnetism works through the brass, so the touch switch never touches the water. It is also clever that the lock nut (left) also has a magnet. The magnets are aligned so that they repel each other. The piston moves forward and the lock nut magnet is pushed back. No spring clogged or corroded! When the flow stops, the magnet becomes strong enough to push the plunger back and the switch deactivates. The plunger moves about 1/4 inch, which is enough to activate the switch. And once the pressure is released, the other magnet is pushed back hard enough to return the piston to the normally open position. no features, no critics. Just something to understand. The plunger has no seal, so very little back flow is possible when seated. This is NOT a check valve. That being said - it doesn't allow MUCH flow to the back. In my application I need to record the flow from a pressure vessel. However, the water must also (slowly) flow back to the pressure vessel. So it CAN limit the flow rate for the tank to full - but since I've never gone that far I can't confirm that. All I can say is that reverse flow airflow is limited. The arrow indicates the flow direction. This absolutely works with the arrow parallel to the ground. will probably work with the arrow pointing up, but not as adept is independent of flow rate because the flow has to lift the weight of the piston. This MAY work with the arrow pointing down as the reflector magnet seems to be holding the plunger on my desk and the switch won't close. But it takes very little force to move the piston because the weight of the piston is pulling "down" and the repulsor magnet is pushing all the time. If the permanent magnets ever weaken in strength, holding them in the open circuit position may not be sufficient. Should give 5 stars as it's an easy and convenient thread change but miscut threads have had me dropping it. up to three. Even if I had a BSP adapter - I don't think it would screw in because of the square cut of the thread. Square threads are commonly used on machine drive parts so either the die was damaged or someone didn't really know what they were doing when they turned on the tap.
