Introduction
The D118 Ultrasonic Flowmeter is an advanced transit-time ultrasonic flow meter that uses the latest digital technology and low voltage broadband pulse transmission design. It is primarily designed for full pipe clean liquid applications, but is also tolerant of liquids containing small amounts of bubbles or suspended solids, making it suitable for most industrial environments. Compared with traditional flow meters or ultrasonic flow meters, D118 has the remarkable features of high accuracy, high reliability, high capability and low cost. In addition, it has the following advantages: it is designed with TVT technology, has fewer hardware components, low-voltage broadband pulse transmission, and low power consumption. The user interface is clear and friendly, and the operation is easy. Provides daily, monthly and annual total flow, parallel operation of positive, negative and net flow totalization, with proportional factor (range) and 7-digit display, total total pulse and frequency output transmitted through relays and open collector.
