Product Introduction
D118 Ultrasonic Flowmeter is a state-of-the-art transit time ultrasonic flowmeter. Designed using the latest digital technology and low-voltage broadband pulse transmission.
●TVT technology designed.
●Less hardware components, low voltage broadband pulse transmission, low consumption power.
●Clear, user-friendly menu selections make flowmeter simple and convenient to use.
●Daily, monthly and yearly totalized flow.
●Parallel operation of positive, negative and net flow totalizes with scale factor (span) and 7 digit display, while the output of totalize pulse and frequency output are transmitted via relay and open collector.

FAQ
Q1: Can D118 Flow Meter track water usage?
A1: Yes!It's the ultimate smart water meter designed to transform the way you use water and your budget. Use this water meter to conveniently monitor and track water usage and detect water leaks in real time!
Q2:How does an D118 Environmental Flow Tracking Flow Meter work?
A2:It calculate flow rate and volume by sending ultrasonic pulses into the fluid and measuring how long it takes for the detector to receive these pulses.
Q3: What are the three 3 types of flow meters?
A3:Different types of flowmeters include differential pressure flowmeters, velocity flowmeters, positive displacement flowmeters, mass flowmeters and open channel flowmeters
Q4:How does an ultrasonic flow meter work?
A4:Ultrasonic flow meters work by measuring the propagation time required for sound to propagate in both directions between two transducers, alternately transmitting and receiving ultrasonic pulses between the two transducers
Q5: How to test the accuracy of a flow meter?
A5: Accuracy is determined through the calibration process. For accurate calibration, a calibration stand is required. The stand requires a reference flow meter with an accuracy higher than the expected accuracy of the meter under test. Typical accuracies of reference meters are + or - .
