Schneider Electric 67 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Wireless Basics Terminology Amplitude is the power of a radio signal >Often represented in decibels (dB). >3dB = 2 x Power, 10dB = 10 x Power, 20dB = 100 x Power >dB is a logarithmic ratio that simplifies calculations. Transmitter Power >Measured in Watts or dBm (dBm is relative to 1mW ) >dBm=10 Log P2/P1 where P1=1mW >1 Watt = 30 dBm, 100 mW = 20 dBm >A 1 Watt (30dBm) radio transmits a stronger signal than a 100 mW (20dBm) radio >Transmitted Power dissipates in space losing 6 dB every time the distance is doubled. Receiver Sensitivity >Measured in uV or dBm and represents how weak a signal the receiver can hear >Sensitivity of 96 dBm is 3.51 uV Antenna Gain >Measured in dBi (dB relative to an isotropic antenna) or dBd (dB relative to a dipole) Conclusions >Transmitter and Receiver parameters are always relative to a level (dBm) >Signal Loss and Attenuation are absolute values (dB) >Radio performance is a combination of transmit power AND receive sensitivity. >A radio with 104 dBm receive sensitivity will hear signals that a 96 dBm radio will notno matter how strong the signal was when it was transmitted. >Note that a radio with 104 dB sensitivity will operate at approximately twice the range of 96 dB radio. 6 dB = double the range.

Schneider Electric 68 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Wireless Basics Free Space Loss Represents the ttheoretical RF loss (attenuation) (in dB) over a distance in a vacuum. Real World path loss will always be higher Calculated with this formulae: L = Free Space Loss (dB) r = distance in meters = wavelength in meters

Schneider Electric 70 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Wireless Basics RF coverage, planning and the level of infrastructure required differ depending on the spectrum utilized.

Slide 71

Schneider Electric 71 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Radio Path Study A radio path study is a valuable analysis tool used to determine radio signal loss over a terrain profile. It can help in determining critical system components like radios, antennas, towers, repeater stations and system layouts. A typical study is generated from customer- supplied GPS coordinates utilizing specialized software tools. As part of our ongoing program of dedicated customer support, we offer Radio Path Study services free of charge: Complete the excel-based Path Study request at Path Study Request FormPath Study Request Form Submit form to pathstudy@controlmicrosystems.com (allow 2 weeks for study)pathstudy@controlmicrosystems.com

Schneider Electric 75 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Accutech Products in WWW Level These wireless tank level field units use a submersible pressure sensor to provide hydrostatic level of a vented tank or well. Specific-gravity correction and all common level units are offered. Flow Open channel flow may be measured from liquid level using the DP20 wireless differential pressure sensor. When the DP20 operates in Open Channel Mode it may be configured with a K factor to report directly in units of flow. Channels with irregular dimensions can be accommodated using an additional 22-point custom curve.

Schneider Electric 76 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014 Accutech in Irrigation The irrigation market is perhaps the best suited to Accutech, with monitoring points almost always located at a distance with no possibility for power. Current opportunities on the US West Coast include well/reservoir/aquifer/canal level monitoring. Accutech SL10 submersible level field units are the product of choice for these applications. The SL10 wireless field units use a submersible pressure sensor to provide hydrostatic level up to 100 (30m) depth. Accutech SL10 Submersible Level

Schneider Electric 77 | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31 st, 2014Schneider Electric Telemetry and Remote SCADA: Accutech Product Line Overview Accutech in Treatment Plants Treatment plants often require monitoring points which are either at a distance or in areas where wiring is problematic, examples include: Digester gas applications (i.e. volume measurement, flow, DP) Headworks monitoring (i.e. rpm measurement of rotating screens) Pressure and level. While in-plant applications are not a prime target for Accutech there do exist processes which remain difficult to wire / service that are outside the plant.
