" The Data Acquisition System (DAS) must be a high accuracy and reliability real time portable surface data gathering, recording, processing and transmitting system. It is capable of monitoring several sensor points of data input.
a) Function:
● Polls up to twenty four channels.
● Calculates true pressure and temperature, Flow for each sensor from calibration data.
● Stores the pressure and temperature, flow values in non volatile memory.
● Interface to two field computers (also a part of the DAS) via a plug in USB cable or communication link.
b) Online function:
● Data acquisition mode programming
● Real time point sampling and display on field computer or hand held terminal.
● Remote data view solution through internet connection.
● Remote data access through IP Address from muti-users.
● Dump of stored data to field computer.
