Daniel Mark III Electronics - Ultrasonic Flow Meter Transmitter
This innovative electronics platform improves the speed and simplicity of managing ultrasonic measurement information, saving time and assuring measurement integrity. All transducers are sampled 32 times per second and measurement is updated every ¼ second.
Mark III Electronics firmware utilizes Linux operating system, enabling fast and easy access to data including alarms, configuration changes and flow dynamics in seconds. In addition, this scalable platform improves low-flow performance and the ability to detect and process ultrasonic signals in the presence of high-frequency valve noise.
Mark III Electronics supports the following communications:
- Two individually configurable 115 Kbps serial communication ports
- RS-232 and RS-485 half and full duplex
- Optional Ethernet connectivity
- Polling from multiple users simultaneously using Ethernet
Mark III Electronics design is compatible with all Daniel ultrasonic transducers and meters, reducing costs with fewer spare parts in inventory. This platform includes:
- CPU
- Field Connection Board
- I.S. Interface Board
- Option Board (Series 100, Series 100 Plus Expansion Board, or Expandion Board with HART)
- Acquisition Board
