Fm15-25 series rotatory wing dry transmitting water go with the flow meters are used for measuring the volume of cold/hot potable water passing through the pipeline and remotely transmitting the sign of the water quantity to far flung monitoring equipment.
I am seeking to installation a low-flow switch (circuit is open beneath zero.1 gal/min, closed above that) as a safety measure on an immersion heater, but i have some questions about the setup i have come up with (i have only taken an intro to electronics physics class). I've connected a picture of the diagram of the machine and blanketed links to the relevant product pages beneath. My questions are: do i need to have a few kind of resistor or load in the flow switch circuit between the fuse and transfer so that there is something for the voltage to drop throughout whilst the drift is too low and the circuit is open? Similarly, would i need a resistor or load of a few kind among ssr1 and fuse 2 for the equal purpose? Ultimately, i want the contemporary inside the waft transfer loop to be underneath zero.7 amps. I see from the ssr specs on the website under that the impedance rating is 36,000 /-20 ohms, so with a 12 vdc electricity supply and 36 kohms, i calculate a modern of zero.3 ma. Am i calculating the cutting-edge for the flow transfer circuit correctly? Thank you!.
tf50-p glide switch is used to prove waft in liquid strains using water, ethylene glycol answers, or different drinks like minded with brass and phosphor bronze parts. The spdt contact transfer is activated by the drift of liquid via the pipes. The set factor is adjustable.
The duct air glide switch gives feedback of air glide in hvac duct work. It can be related directly to the control device as a feedback point or may be directly interlocked to save you operation of heating and cooling device whilst there's no air waft. Stainless-steel paddle resists corrosion. Adjustable spring anxiety screw permits setting the air go with the flow ride factor. The paddle may be trimmed down for better float applications. The cable enters thru the water tight gland, or the gland can be removed and changed with an emt or flex connector for wiring with emt or metal flex.
