The transmitter can be intrinsically safe, microprocessor-based, and can be provided with alarms and a pulse output for totalization. Plastic-tube rotameters are low-cost rotameters that are ideal for applications involving corrosive fluids or deionized water. ...
When installing a vortex flowmeter in an existing process where the flow range is not known, it is recommended to first make some approximate measurements (using portable pitot tubes or clamp-on ultrasonic devices). Otherwise, there is no guarantee that a line-size vortex meter will work at al...
4. Ultrasonic sensors Another non-contact type sensor is the ultrasonic sensor that is used to calculate the distance and the velocity of an object. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. These sensors...
Thesetup()function runs one time, every time you power on your Arduino. This is where you set up everything you need for your program, like what pins should be inputs and outputs. Theloop()function starts after the setup() function has finished and runs over and over again until you ...
By measuring the difference in propagation time of the ultrasonic waves from the transmitter to the receiver, the wind speed can be calculated. How to measuring wind direction? Measuring wind direction is accomplished by comparing the difference in propagation time between two pairs of ultrasonic tra...
Ultrasonic obstacle sensor consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. The point when something moves in the zone secured the circuit’s fine offset is aggravated and the buzzer/alarm is triggered. ...
