Ultrasonic Flow Meter PCE-TDS 100HS
Measures liquid flow velocity in pipes and tubes with a diameter of 20 … 108 mm / ≈ 3/4 ... 4 in
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.
Note: To transfer data to a computer, SOFT-PCE-TDS software is required. The software is sold separately - see accessories for details.
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.
