Many powders and bulk solids are known to sit erratically in storage. Sometimes they flow freely. Sometimes, not. When slide gates are supposed to be closed, but aren't, loose material falls and becomes waste. Feeders and conveyors should deliver bulk materials into a process—but how do you know for sure if it was ...
At the same time, through the use of advanced technology such as the Doppler effect, can improve the measurement accuracy and stability, suitable for the flow measurement of high precision requirements of the occasion. ...
Ground Speed Radar: The ground speed radar for land-based dynamic vehicles is based on Radar Doppler technology. It consists of a radar frontend with planar antennas continuously emitting electromagnetic waves at 24 GHz. Due to the movement of the sensor onboard the vehicle, the frequency of the back-scattered waves is Doppler shifted. ...
Mark Moehring, the inventor of transcranial Doppler ultrasound. They thought ultrasound technology was a potential solution, given it is a highly accurate, well-known, and safe technology. ...
When considering the critical performance differences between polarized aerosol lidar such as Micro Pulse LiDAR (MPL) and Doppler Wind LiDAR, it is clear that MPL is the only realistic remote sensing technology for mapping aerosols. ...
The Flo-Dar sensors combined digital doppler radar velocity sensing technology with ultrasonic pulse echo level sensing to remotely measure open channel flows. ...
Ultrasound is sound generated above the human hearing range - above 20 kHz. Both Doppler and Transit Time flowmeter technologies are called "ultrasonic" because they operate far above the frequencies or sound range that we can hear. ...
Remote data transmission and maintenance of measurement systems via GSM-mobile network Solution OTT SLD 2.0 – Side Looking-Doppler sensor for the measurement of local flow speeds (index velocity) Stationmanager LogoSens2 for monitoring, processing, storage and transmission of all measured values Pressure probe OTT PS1 for longterm-stable water level measuerement Solar ...
Monitoring Solution OTT SLD 2.0 MHz Side-Looking-Doppler-Sensor for measurement of local velocity of flow (index velocity) OTT CBS – compact bubble sensor for longterm-stable water level measurement Stationmanager OTT LogoSens2 for monitoring and storage of measured data, calculation of discharge quantities and control of remote data transmission via analogue modem ...
Solution OTT ADC – Acoustic Digital Current Meter – for the precise and reliable measurement of point velocities and flow rates Advantages Reliable measurement of flow velocity with latest ultrasonic- Doppler technology High versatility thanks to compact instrument size and light weight Quick data processing thanks to the included user software Summary ...
The operators decided to choose a horizontal Doppler-flow sensor with an OTT SLD and entrusted the experts of the company “ALLTEC Automatisierungs- und Kommunikationstechnik GmbH” with the construction of a measuring site and the connection with the central control and communication system. ...
Task Online measurement of water level and flow velocity with discharge calculation according to the velocity-index-method at the stations in Plau, Banzkow and Malliß Data storage and prompt supply of all data for the management tasks of the water and navigation authorities or for the current requirements of other users (e.g. regional authorities) Remote data transmission and maintenance of ...
Ultrasonic flow meters are divided into two measurement technologies: Doppler & transit-time. These technologies are available in two styles: 1) clamp-on (non-intrusive to the piping system) or 2) wetted (inserted into the pipe with the sensors exposed to the flowing fluid). ...
