Wellhead monitoring System SiamMaster-mini GSM - i

General concepts

the system is based on the wireless sensors and smartphone;
smartphone functions as a visualizer and a recorder for sensors of different applications (level monitoring, dynamometering, pressure monitoring and so on) with wireless connection. The sensor has an integrated power source without a display, a keyboard;
smartphone has IP68 protection;
the power system: built-in lithium battery (charged with a network adapter or car's lighter socket);
full charge time, not more than 7 hours;

* Supply of separate sensors is available

the intuitive interface of I-Service programme allows simple and quick preparing and conducting measurements;
sensors (echometering and dynamometering) have wireless connection to smartphone (there is no time waste on cable connection, cable faults are avoided because of its absence, reliability is improved without cables);
the wide operating range allows controlling and monitoring the measurements on the smartphone display at a large distance from a wellhead (up to 50 meters), including the ability to carry out multiple repeated measurements, i.e. perform measurements from vehicle;
installation time of sensors is minimized (attachable to a polished rod ratchet screw, small size, wireless connection);
GSM channel provides data transfer to a remote computer through email, messengers or other interfaces immediately after recording the measurements;
the user interface is very simple: it indicates accumulator charge only. Measurement scheduling, initiation, visualization and storage are remote and performed with a terminal. Data transfer is wireless;
the smartphone provides storage of a large number of measurements (depending on internal memory capacity) and transfer of collected data to a relevant database;

wireless sensors connection;
a ratchet screw in dynamograph instead of initial power setting upon light-emitting diode readings;
I-Service software is based on OS Android;

the connection has interference protection and large distances (usually – 50 meters);
used Bluetooth communications protocol provides connection with any Android smartphone having Bluetooth module;
the presence of GSM channel to transfer data;
the possibility to charge the battery under subzero temperature (from –20 °С);
