Instrument Overview

The ISS-100H handheld ultrasonic flowmeter employs a low-voltage, multi-pulse transmission circuit, significantly enhancing measurement accuracy, service life, and reliability. Its dual-balanced signal differential transmission and reception circuit effectively shields against interference from strong sources such as variable-frequency drives, TV towers, and high-voltage power lines. It features a built-in rechargeable nickel-metal hydride battery that enables continuous operation for over 12 hours. Additionally, it incorporates optimized intelligent signal adaptive processing, eliminating the need for users to make any circuit adjustments.

Performance Features

1. Chinese-character LCD display

2. Non-contact measurement

3. Built-in data logger

4. Built-in rechargeable battery

5. High-precision measurement,

6. Wide measurement range

7. Small in size and lightweight.

8. RS-232 standard data interface

Working principle

When an ultrasonic beam propagates through a liquid, the liquid’s flow will cause a slight change in the propagation time; this change in propagation time is directly proportional to the liquid’s flow velocity. At zero flow rate, the time required for the two sensors to transmit and receive the sound waves is exactly the same (this is the only technique that can actually measure zero flow). However, when the liquid is flowing, the propagation time of the sound wave traveling against the flow direction is longer than that of the sound wave traveling with the flow direction.
