Calculates flow velocity without the need to cut into existing pipework
Time of Flight
- Ultrasonic transit time measurement
- Intuitive menu with easy configuration
- Flexible measurement
The Orakel Time of Flight Sensor is a non invasive liquid flow measurement tool that uses ultrasonic technology to calculate flow velocity without the need to cut into existing pipework.
How it works
Transit time ultrasonic flow meters send and receive ultrasonic waves between transducers, in both the upstream and downstream directions, in the pipe.
At ‘no flow’ conditions, it takes the same time to travel upstream and downstream between the transducers. Under flowing conditions, the upstream wave will travel slower and take more time than the (faster) downstream wave. When the fluid moves faster, the difference between the upstream and downstream times increases. The transmitter processes upstream and downstream times to determine the flow rate.
Driven by HMI, the intuative menu makes installation easy
Includes a full set of instrument and measurement diagnostics
An integrated signal oscilloscope optimises sensor positioning and diagnostics
Includes an internal database of pipe, fluid and lining materials:
|LINING:||None, Cement, Epoxy, Glass, PP, PVDF, Rubber, Other|
|PIPE:||Carbon Steel, Stainless Steel, Cast Iron, Ductile Iron, Copper, PVC, Aluminium, Asbestos, Fibre Glass – Epoxy, Other|
|FLUID:||Water, Sea Water, Kerosene, Gasolene, Fuel Oil, Crude Oil, Freon R134a, Freon R22, Diesel Oil, Castor Oil, Peanut Oil, Ethylene glycol, Glycol/Water 50%, Alcohol, Other|
Built-in fluid parameters allow calculations to compensate for speed of sound, density, viscosity, specific heat capacity and temperature (if temperature is known from optional temperature probe).
Liquid can be measured in M, m3, USgal, mg, cf, bbl and Imp bbl. All measured values can be selected as flow rate per second, minute, hour or day and are automatically totalised.
An optional GSM data-logger can be added and date sent to an online portal for detailed analysis
