It is ideal tofullevaluate performance of in-line flow meters and can be installed,calibrated and started-up in minutes. Use it for projects where apermanent flowmeter is not required or to temporarily replace installedflow transmitters.The PDFM 5.1 ultrasonic sensor ison the outside of a pipe.Anclampedacoustic pulse is reflected back to the sensor from particles or gases inthe flowing liquid.The flow rate of any fluid can be measured as long as itcontains air bubbles or solids. It is ideal for wastewater, slurries, sludge,and most chemicals, acids, caustics, and lubrication fluids.With its internal battery the PDFM 5.1 can be operated all day and thenrecharged overnight. For continuous use it can be powered by a supplied110-240VAC wall plug adapter.A300,000 point data logger is built-in. Fast, Easy Flow MeasurementUltrasonicwith Non-ContactingSensor   Quick, Easy Flow Measurements from Outside a Pipe Each Greyline PDFM 5.1 comes complete withcarrying case,rugged watertightstrap-on sensor and stainless steel mounting kit.Use the simple 5-key menusystem to select units of measurement and to calibrate to any pipe diameter ½”(12.5 mm) or larger. Simple start-up and Calibration Sensor mounting and a full calibration can be done in just a few minutes. It isfast and easy! Put coupling compound() on the sensor facegelincludedandmounton the outside of a pipe with the stainless steel mountingthe sensor bracket (supplied).fiveUse the-key calibration system to enter pipe diameter and to select your choice of engineering units (gallons, litres etc.)The PDFM 5.1will immediately begin to display, transmit and totalize. No Calculations - No Programming Codes Select your choice of display units: the PDFM 5.1 will display and totalize flow volume in gallons, lites, cubic feet or cubicr meters. If you change from one measurement system to another, the PDFM 5.1 will automatically and instantly calculateand convert the flow display and totalizer.alibrate topipe size using the keypad to enter inside diameter.Cthe Built-in0,000 point Data ogger 30land PC Software Set up the PDFM 5.1's data logger to store time and date-stamped flow values from 1second tominute intervals.

Greyline Logger softwareUSBt(included)displays data in both graph and table formats andexports to graphic or text file formats for use in other programs. “Sleep Mode”for Extended Data Logging onBattery Power  Sleep mode extends battery life for long-term data logging atlocations whereAC power input is not available. Between logging intervals the flowmeter drops into a stand-by mode untila flow reading is requested by the data logger. Flow rates are sampled continuously for 10 seconds and then the PDFM5.1 returns to sleep until the next logger point is required. With 5 minute sample intervals the PDFM can data log for about18 days on battery power. New Signal Processing for reliableAccuracy  The PDFM 5.1 Doppler flow algorithm filters out background noise andinterference.The high speed digital signal processor discriminates againstweak and distorted signals. When the processor cannot measure accuratelythe meter will display zero flow and indicate low signal confidence.

Because the sensor is so easy toinstall you can test any application and pipe material in a few minutes. How it Works The PDFM 5.1 ultrasonic sensor injects highfrequency sound through the pipe wall and intothe flowing liquid. Gas bubbles or solidssuspended in the liquid reflect the ultrasonicsignal back to the sensor. When this soundis reflected from moving bubbles or particlesit is returned to the sensor at an alteredfrequency.This frequency shift is called theDoppler effect.The PDFM 5.1 continuouslymeasures the change from it's transmittedfrequency to the received frequency toaccurately calculate flow.
