Mobrey flow computers/signal converters
Series 795x
Mobrey's range of flow computers and signal converters are used in a wide variety of applications ranging from fiscal transfer systems to gas blending operations. The computers take inputs from a variety of sources and then perform all the appropriate calculations. The results can be read on the integral display and also transmitted to a remote workstation. The 795x range comprises three distinct hardware platforms, which can be loaded with any one of a variety of application software. This structure offers the benefits of using standard, proven hardware whilst providing maximum application flexibility.

Notes:
1. Dual Pulse
2. I/P's == Inputs; O/P's == Outputs
3. Each PRT (RTD) takes one analog input channel
4. May be used as extra Status Inputs
5. Port 1 = RS232; All other ports RS232 or RS485
6. Uses 2 or 4 analog inputs
