Detail Boiler water heaters Accessories Hall sensor meter off water dispenser

hai kak. Mohon maaf untuk minimal order 20 ribu ya kak baru bisa kita proses, diluar ongkirFeatures:

1, the product appearance of lightweight flexible, small size, easy to install.

2, the impeller internal inlaid stainless steel beads, never wear.

3, seal with the structure under the force never leaks.

4, the Hall element imported and treated with silica gel waterproof apron strengthened to prevent water, never aging.

5, all raw materials are in line with ROHS testing standards

6, standard G1 / 2 thread installation interfaces simpler and more durable.

I. Introduction:

Water flow sensor consists of a plastic body, the flow of the rotor assembly and a Hall sensor.
It is installed in the water heater inlet end for detecting the flow of water when the water flow through the rotor assembly,
A magnetic rotor and the flow speed is adapted to change, the Hall sensor output corresponding pulse
Signal feedback to the controller, the controller is determined by the size of the water traffic regulation.
Caution:
Non-violent shocks and chemical erosion.
Prohibited throw or collision.
Medium temperature should not exceed 120 degrees
Second, the output waveform: output signal -NPN square wave

Third, lead the way:
IN 1 red then positive
2 yellow OUT signal output line
3 black GND to negative
4 green R temperature sensors (3950K 50K or 3950K 15K please customers choose according to their own requirements )
Frequency: F. The Q = 7.5 * (L of / the Min) error: 2%

A flow rate of 1L / min for the column, that is, 7.5 * 1 * 60 is equivalent to the number of liters of water flowing through the pulse output voltage: 3.5-24VDC, current can not exceed 10mA, Ends stream output 450 liters of water a pulse

That constant frequency calculation = 7.5 * Unit Flow (L / min) * Time (seconds)

Flow range: 1-30L / min
