Ultrasonic flow meter incl. Temperature data logger
according to the transit time difference method / For determining flow velocity and flow / Measurement method for liquids that are as homogeneous as possible
Calculation of flow velocity according to the transit-time principle follows the equation:
v = measured velocity
T1 = run time of the ultrasonic signal in the flow direction
T2 = run time of the ultrasonic signal against the flow direction
L = length of the ultrasonic wave
α = ultrasonic signal angle to the flow
The transit-time principle requires pipes to be full and have no bubbles and no particles.
Each PCE-TDS series meter is assembled by PCE Instruments in Germany and and factory-calibrated (without any documentation). The reference display of the in-house test stand used by PCE for calibration has a valid DAkkS calibration certificate. This ensures traceability to the Physikalisch-Technische Bundesanstalt (PTB) German national standard. Please note that the meter’s measured values depend on the pipe geometry, material and coating; the medium type, temperature and speed; and the sensor type and measuring method.
