TDS – 100H series ultrasonic flow meter

APPLICATION:

• Non invasive measurement of velocity of liquid flowing in a pipeline.

FEATURES:

• Accuracy: better than 99%.

• Repeatability: Better than 98%.

• Installation: Clamp on.

• Display: 4 x 16 English letters.

• Output: RS232.

• Weight: .53kg.

• Power: 100 – 230VAC built-in Ni-H rechargeable battery.

• Battery life: 10 hours.

MEASUREMENT PRINCIPLE:

The TDS – 100H series ultrasonic flow meter uses the well known Transit-Time measurement principle plus propriety signal processing and ultrasonic transceiver technology.

When an ultrasonic signal is transmitted through the flowing liquid, there is a time difference (transit time) between the upstream and downstream transducers which is proportional to the flow velocity according to the formula below.
