|Welcome to the June Newsletter - we would like to share the latest QTech updates with you.|
|The new WRTU for DATRAN VI SCADA systems is coming soon.|
This low cost, low power RTU integrates remote I/O directly into DATRAN or even into an existing XL4 Plus RTU. Using an integral 900MHz radio, the WRTU is ideal for solar powered sites where flow meter or status data is needed.
A release package will be sent out later in the year, but please contact our sales team now so we can understand your specific applications and ensure we forecast your requirements.
Will a WP2P System Work Here?
|This is a question we are often asked and wanted to share an example of how to determine it for a Wireless Point to Point radio system.|
Firstly, plot the positions on Google Earth (or similar) - this gives you the path length and elevation profile - both of which are important.
In this example the distance is 2.1km, the tank is about 10m higher than the pump and there are no significant obstructions to the radio path.
This is a perfect situation for our low power radio systems, with optional antennas and a solar power supply at the tank site.
More detailed and formal RF surveys are always needed for difficult links and challenging situations. We often conduct RF surveys for farm irrigation systems using our Water-Insight fixed grid irrigation control systems as the hilly terrain is often a challenge and would require radio repeaters.
|Support for floating-point numbers was introduced into DATRAN recently. This has been really well received by our technical system integrators, and the opportunities it now provides for system integration with devices such as turbidity meters and UVT. |
One expert recently said "this is fantastic news, we need to use this for the new generation of flow meters we are using".
Not only can floating-point be used for the regular 4 byte single precision, it can also be used for 8 byte double precision (equivalent of 64 bit) applications. We encourage everyone to upgrade the XL4 Plus RTU firmware to v7.16 to take advantage of the latest features & fixes.
