The REAM HMI is a user-friendly data acquisition system that reads data from electronic sensors and displays the data on an 9” TFT touch screen, which acts as both an input and an output device. The system records the data on solid state Compact Flash memory and allows remote monitoring of the data.



The system is made of two main parts, REAM is a microprocessor based data acquisition board, which collects data from electronic sensors, digitise the readings, and supply the appropriate excitation voltage to the sensors. The HMI communicates with the REAM board to retrieve, display, and store the data.



REAM has analogue, counters (frequency), and quadrature channels. The analogue channels accept signals from sensors with 0-5 vdc, 0-10 vdc, or 4-20 mA output. The counters accept pulse signals produced by proximity switches or magnetic pickups. All supplied sensors are intrinsically safe, suitable for use in well testing applications.


In addition to the REAM board, the HMI can communicate with many other devices such as NuFlo MC-III Flow Analyser, Modbus enabled device, serial devices, PLCs, etc.


The outputs are available on Web Pages, they can be viewed remotely on a Local Area Network (LAN) or even a Wide Area Network (WAN), provided that proper Internet connections are available. There are many other features in the HMI and these can be tailored to client’s request.
