Aquaread Point Green Telemetry

  

Point Green is a compact Logger/RTU device with integrated battery, a 3G modem with GPRS fallback, internal and/or external antenna, digital and counter inputs, Modbus and SDI-12 master capability and a submersion sensor.

Point Green provides real-time remote monitoring of up to 3 sensors. It includes support for digital and counter inputs. The Point Green can also communicate with third-party serial devices over Modbus (using RS232 and RS485) or SDI-12. In addition to the multiple configuration options the Point Green offers local monitoring of battery voltage, cellular signal strength and ambient temperature.

The RTU offers a plug and play solution that minimizes the need for additional site visits, with remote management functions including remote firmware upgrade enabling associated cost-savings. It can store thousands of records in memory for later retrieval by SCADA systems.

The Point Green was designed from the outset as a self-contained, low cost fit-and-forget unit for use in
harsh and hazardous environments in remote locations. Its design exploits mainstream technologies
which help to minimize costs whilst at the same time ensuring reliability and a long product life. The
latest developments in low power technology are used, allowing the Point Green to derive all the power it
needs (including sensor power, if required) from an internal battery pack. This, together with an integral
3G modem, ensures a long service life with low infrastructure costs.
