NBSANMINSE SMF-S401 High Precision Coffee Machine Flow Meter Sensor Connected To 6mm Hose Water dispenser
The images shown are not all the actual item and are for your reference only
1, The product looks lightweight and flexible, small size, easy to install.
2, impeller inlaid stainless steel shaft, wear-resistant forever.
3, the seal with the upper and lower force of the structure never leaks.
4, Hall components imported, water-proof design, to prevent water.
5, multi-pole high temperature stainless steel 3 times higher than the traditional precision.
6, all raw materials are in line with ROHS testing standards.
Water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and Hall sensor.
It is installed in the water heater inlet, used to detect inflow, when the water flow through the rotor assembly,
Magnetic rotor rotation and speed with the flow rate changes, the Hall sensor output corresponding pulseSignal, feedback to the controller, the controller to determine the size of the water flow, the regulation.
Severe impact and chemical erosion are strictly prohibited.
Do not throw or crash.
Medium temperature should not exceed 120 degrees
Second, the output waveform: square wave
Lead the way:
1 Red IN then positive
2 Yellow OUT signal output line
3 Black GND connected to the negative
Frequency: F = 98 * Q (L / Min) Error: ± 2% The flow rate of 1L, that is, 98 * 1 * 60 is equal to the number of pulses flowing through 1 liter of water. Voltage: 3.5-12VDC, current can not exceed 10mA, finished a liter of water output 5880 pulses
Ie frequency calculation = constant 98 * unit flow (L / min) * time (seconds)
Flow range: 0.3-6L / min
Pulse characteristics of F = 98 * Q, F said the frequency, Q said the flow unit liter / min, then the diameter 5-7mm silicone tube, diameter 7mm, inlet diameter can be done 1.5-4mm, buyers can according to their own flow Range selection. The inner diameter of 1.5mm flow range is 0.2-2L / min, the inner diameter of 3mm flow range is 0.3-4L / min, the inner diameter of 4mm flow range is 0.3-6L / min.
Commonly used diameter is 1.5mm, other inner diameter to be customized, contact the seller before the shoot
