INTRODUCTION
The PM052 / Tscada-Aqua s an advanced wireless RTU designed for use with smart senors (Insitu Inc.) Water Qualities and Level snsors. The custom software allows for very accurate measurement of water qualities sensors using digital interface to allow for real time sensor compensation (such as temperature, PH, pressures) in order to get compensated reading at the site and the data send back to the server for real time monitoring and alert.
Currently Support Insitu probe (existing 4-20mA sensor can be accommodated via the inbut 8 channel of 16bit Analog input)
The PM052 logs the readings and display the sensor reading on the LCD, as well as maintain reliable wireless communication to send data to the server for web viewing and download as well as analysis purpose.

LCD Display And Keypad Entry

Large 20 char x 2 line BackLit LCD shows system status, date and time as well as all status of outgoing server messages, and  provide system diagnostic information.

IO DESCRIPTIONS AND ALERT LIMIT, ENABLE

Each Input Channel descriptions, Alarm Hi and Low can be edited and invidually Enable / disable. Digital Alert can be enable for High Change, Low Changed or both. Analog Alert can be trigger for Alarm Hi or Alarm Low.
External Buzze rand Beacon turn on time is programmable (default is 1 minute)

Reliability of sensors

As digital sensor is used, reliability of the sensor measurement is maintain and digital calibration is used. This eliminate calibration and zero/span variance between sensors and Logger and ease setup.

POWER MANANGEMENT

PM052 is design to optimized on low power consumption, as such it requires very low battery capacity even when continuously measures and sending data, PM052 draws no more than 1.2W @12V in worst case. As opposed to 4-20mA sensors the digital sensor draws very little power. This reduce the size of the battery and solar panel greatly, the system can continue to run for 14 days even without sunlight.
