2. They are solid state, with no moving parts, unlike mechanical switches where debris can get jammed and cause unreliability.
3. Cost-effective.
4. A wide variety of power output is available, allowing the sensor to switch lower power equipment directly, eliminating the need for costly interfaces
5. Easy to install, saving assembly time.
6. Very robust which permits use in a wide range of fluids.
7. Housings, cabling, and connectors are made to your requirements

Package Includes:

1 x 24V Capacitive Contactless Externally Liquid Level Sensor

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.

Gravity: Analog TDS Sensor/Meter for Arduino is an Arduino-compatible TDS Meter Kit for measuring TDS value of the water, to reflect the cleanliness of the water. TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing. You may also check Liquid Senser Selection Guide to get better familiar with our liquid sensor series.

TDS (Total Dissolved Solids) indicates that how many milligrams of soluble solids dissolved in one liter of water. In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.

TDS pen is widely used equipment to measure TDS value. The price is affordable, and it is easy to use, but it is not able to transmit data to the control system for online monitoring to do some water quality analysis. The professional instrument has high accuracy and can send data to the control system, but the price is expensive for ordinary people. To this end, we have launched an analog TDS sensor kit that is compatible with Arduino, plug, and play, easy to use. Matching with Arduino controller, you can build a TDS detector easily to measure the TDS value of liquid.
This tds sensor supports 3.3 ~ 5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with a 5V or 3.3V control system or board. The excitation source is an AC signal, which can effectively prevent the probe from polarization and prolong the life of the probe, meanwhile, increase the stability of the output signal. The TDS probe is waterproof, it can be immersed in water for a long time measurement.

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
