Описание

Full Copper G3/4'' DN20mm 2-45L/min Circulation System Water Flow Sensor Flowmeter 35*60mm Length

1: Specification Drawing

Hall effect: pulse signal output

Housing material: brass

Installation method: any direction

2: Technical Parameters

Working principle

Water flow sensor is the use of the Hall element to measure the Hall effect magnetic sensors of physical quantities. Water flow sensor mainly consists of copper body, water the rotor assembly, steady flow component and Hall sensors, installed in the water heater inlet side used to detect the size and water flow off.

Working media: water, not more than 60 °C

Working voltage: DC4.5-18V,(24V can be customized)

Rated voltage: DC5V

Max operating current: 10mA

The output pulse high level: In 5 V rated voltage, the output of the high level requirements in 4.5 V above;

The output pulse low level: In 5 V rated voltage, the output of the low level requirements below 0.5 V.

The output pulse duty ratio: In the rated voltage, the output pulse occupies emptiescompared to 50%±10%

Insulating property: Dielectric resistance>100MΩ

Electrical strength: AC500V 50Hz(Don't breakdown or flash winding)

Flow range: 2-45L/Min

Withstand voltage: not more than 1.75MPA

3: Flow Range Characteristics

1)Instant Flow Pulse Characteristics: F=8.1*Q(flow range)-3±10%

2)Accumulated Flow Range Pulse Conversion Proportion: 1L water=477pulse ±10%

4:Installation Instructions

1) its characteristics may change when a magnetic material or to produce magnetic material near the sensor.

2) Enter the sensor in order to avoid particle, sundry, the sensor must be installed filters the water entry.
3) The installation of water flow sensor need to avoid strong vibration and shaking environment, so as not to affect measuring accuracy of the sensor.
4)Please do not disassemble without authorization flow sensors in case of damage, water flow sensors to disassemble a are out of place in the warranty scope.
5) Ever and Never used the structured sensor, when used for direct replacement may be not appropriate place, please timely put forward.

5:Connection Mode
RED line for power+
BLACK line for power-
YELLOW line for signal output

6:Application

Widely used in water industrial field, thermostatic water heater, boiler, water dispensers, coffee machines, hot card machines, steam equipment, water system, the campus card sales, selling self-help water systems, water treatment equipment, cooling systems, mechanical equipment, instrumentation, pharmaceutical equipment, water purifier and smart card equipment.
