YF-DN40 1.5 inch is a plastic body water flow sensor that contains a water rotor and a hall-effect sensor and is used for flow measurement for industrial applications. When the water flows through the rotor, the rotor rolls, and its speed changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. The output of the flow sensor is proportional to the water flow. The more the water flowing more are the pulses.

Features:

1. Accuracy in 1 ~ 120L / MIN  ± 2% inline
2. Flow pulse characteristics F = (0.45 * Q) Q = L / Min meet
3. Low-temperature test at -20’C temperature placed after 72h, at room temperature for 1h, the first measurement accuracy within ± 5% value inline

Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are l Obstruction type (differential pressure or variable area), Inferential (turbine type), Electromagnetic, Fluid dynamic (vortex shedding), Anemometer, Ultrasonic, Mass flowmeter

Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope.

Cable Float Switch is a control device for automatic On/Off pumps, motor and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) I-isolator switch units. Due to its large float casing, the float Switch has a buoyancy that guarantees smooth, trouble-free operation under all conditions. The switch has a double chamber and a final remolding finish to make it absolutely hermetic.

Features: 

1. It can test the pressure of the liquid.
2. The float switch is a switch that regulates fluid level in the tank or well etc
3. The float switch is resistant to water(sewage water) it is relatively capable of being used for oil, most acids and alkalis
4. The float switch is not explosion-proof.

Package Includes:

1 x Square 15M Float Switch For Industry Pump Tank Sensor

The FS1012 MEMS mass flow sensor module measures the flow rate using the thermo–transfer (calorimetric) principle. The FS1012 is capable of measuring a gas or liquid medium. The FS1012 offers key advantages over resistor–based flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal–to–noise ratio. The sensor comprises a “solid” thermal isolation technology and silicon–carbide coating to protect
it from abrasive wear and provides robustness and long–term reliability. In comparison, other sensors typically contain a fragile membrane above an etched cavity for the thermal isolation base. The FS1012 features the sensor fully assembled and wire–bonded out to a 6–pin header. Wetted materials consist of a glass fiber reinforced PA66 resin, epoxy, and silicon carbide.

Applications:

1. Process controls and monitoring
2. Oil and gas leak detection
3. HVAC and air control systems
4. CPAP and respiratory devices
5. Liquid dispensing system

Features:

1. Gas or liquid mediums
2. Robust “solid” isolation technology
