Register water flow is warranted to perform to the accuracy levels set forth in the iPERL Water Meter Data Sheet, for twenty (20) years from the date of Sensus shipment Battery/Components At no cost for the first ten (10) years from the date of Sensus shipment, and for the remaining ten (10) years, at a prorated percentage Complete terms available in G-500 Sensus Warranty Bulletinġ7 History and Data Log Data log Alarm Historyġ5 minutes to 24 hour interval options Peak flow Volume Capacity for 1040 data points ~11 days at 15 minute intervals 2.85 years at 24 hour intervals Alarm History Time of event State of device Again…this is the benefit of having no moving parts to slow the water flow down Typical PD Meter iPERL IPERL gets to 100% accuracy quickly because there are no moving parts Can see the linearity across the entire flow range Typical PD Meter iPERL Typical 20 Year Old PD Meterġ4 iPERL Head Loss Typical PD Meter iPERLĪt 20 GPM the head loss is just over 5 psi for a PD meter and less than 3 psi for iPERL. Complies with NSF 61 Annex F/G, NSF 372ġ3 iPERL Accuracy Curve Typical PD Meter iPERL It should be published in the next 3-6 months.** Exceeds AWWA C-700 and C-710 standards for accuracy and pressure loss.
**iPERL will meet and exceed a new AWWA standard for magnetic flow and ultrasonic meters once it is published. And the material is much lighter so shipping is easier and utilizes less gas. There is no oil used in machining as there is with a bronze product. Not only is the product itself lead-free and environmentally conscious but the manufacturing process to make a composite product is much more environmentally sound than manufacturing bronze.
IPERL Specifications Under Normal Conditions the iPERL is calibrated for flow rates as low as: Sizes Starting Flow Registration (GPM) Low Flow Range (GPM) (+/- 3%) Normal Operating Range (GPM) (+/- 1.5%) Lay Lengths ⅝” 0.03 0.11<0.18 7-½” ⅝” x ¾” or ¾”S ¾” regular 9” 1” 0.11 0.3<0.4 0.4 – 55 10-¾” Composite technology brings together all environmental values Sensus pursues along with the state of the art long-lasting mechanical properties required for a water network meter. Solid state magnetic technology Drive coil creates magnetic field in Remanent technology maintains magnetic field Electrodes in flow tube measure voltage in water Voltage and velocity are proportional iPERL uses velocity value and time to calculate consumptionġ2 Starting Flow Registration Normal Operating Range (GPM) D v = mean flow velocity k = constant factor correcting for geometry B = magnetic field strength D = inner diameter.Sensus Meters Intensive Water Meter TrainingĢ Agenda Features, benefits, value props: iPERL accuSTREAM and SR IIĥ Construction Electronic register and measuring device incorporated into composite meter body Electronic register comprised of a circuit board and a 9- digit LCD display Measuring device = composite alloy flow tubeĦ iPERL Register Face Manufacturing Date Replace by Date Unit Sizeįaraday’s Law Electromagnetic Measuring Principle: Ui (induced signal voltage) = v
