The reason it’s not a great waterproofing level is that IPX7 is a time-limited submersion of only 30 minutes and only one meter. Per Garmin’s own site, I offer the below: So you might be asking yourself at this point how exactly did the Joule get roped into this then? Well, a ...
In this paper, we look into smart water metering infrastructures that enable continuous, on-demand and bidirectional data exchange between metering devices, water flow equipment, utilities and end-users. We focus on the design, development and deployment
Available phosphorus and NO3-N concentrations were determined using the Palintest photometer 7500 tests. The nitrate-nitrogen and available phosphorus loads were calculated by multiplying drainage volumes for each period with the corresponding measured NO3-N and PO4-P concentrations. Total water used by...
