PDFM 6.1 INSTRUCTION MANUAL CARRY CASE The PDFM 6.1 is packaged in an orange IP67 carry case with protective molded foam. The picture below shows how the various components included with the PDFM 6.1 are populated into the molds: Legend... -
Page 5: Internal Battery
CHARGER Included with the PDFM 6.1 package is a mains-powered to USB-C charging adapter rated for 5 Volt & 3 Amp (15 Watt). The power outlet connection type can be changed via the included modular plates. For best results, use the included charger. However, a third-party USB-C cable connected to a third-party charger or battery bank will suffice. -

When connected to a USB storage device, such as the included flash drive, the PDFM 6.1 becomes the host and will transfer data to the storage device. The design of the PDFM 6.1 allows for future deployment of “modules” which will be able to plug in to the USB-C port on the PDFM, and expand its capability. -
Page 7: Transducer & Cable
TRANSDUCER & CABLE The PDFM 6.1 is equipped with a single PSE4-A2 transducer which has an integral 12 foot (3.4 meter) cable ready for connection to the PDFM 6.1 socket. The PDFM 6.1 will be “wet” calibrated against a secondary standard for every order. - Page 8 PDFM 6.1 INSTRUCTION MANUAL KEYPAD (CONT.) Keypad layout and functionality continues as shown and described below: CHECK Button: From Main screen – not applicable In programming menus – will move the cursor back one level. Example: if in the Units/Mode sub menu, CHECK will move back to Main Menu.

USB-C drive. When prompted on the screen via Insert USB, insert your USB-C drive into the meter, and the PDFM will save the file. Pulsar Measurement technical support will occasionally request this waveform file in order to help diagnose and resolve measurement questions. -
Page 20: Sensor Mounting Location
PDFM 6.1 INSTRUCTION MANUAL SENSOR MOUNTING LOCATION The position of the sensor is one of the most important considerations for accurate flow measurement. The same location guidelines apply to Doppler as they do for most other flow meter technologies. VERTICAL OR HORIZONTAL PIPE - Vertical pipe runs generally provide evenly distributed flow. -
Page 21: Sensor Mounting
PULSAR MEASUREMENT SENSOR MOUNTING Prepare an area 2" wide by 4" long (50mm x 100mm) for sensor bonding by removing loose paint, scale and rust. The objective of site preparation is to eliminate any discontinuity between the sensor and the pipe wall, which would prevent acoustical coupling. - Page 22 Warm temperatures, moisture and vibration will accelerate this process. Super Lube ® as supplied with the DFM 6.1 (and available from Pulsar Measurement or home improvement stores) is recommended for semi-permanent installations.

Page 24: Common Questions And Answers
PDFM 6.1 INSTRUCTION MANUAL COMMON QUESTIONS AND ANSWERS The pipe vibrates. Will it affect the flow meter? Common vibration frequencies are far lower than the sonic frequencies used by the flow meter and will not normally affect accuracy or performance. However, applications where very weak Doppler signal is present (when sensitivity is adjusted to maximum and signal strength is low), accuracy may be affected by pipe vibration, or the flow meter may show readings under no-flow conditions. - Page 25 Does the PDFM 6.1 require periodic recalibration? PDFM 6.1 calibration does not drift over time. The solid-state sensor has no moving parts to wear and affect calibration. The Doppler flow technique generates an ultrasonic signal proportional to the velocity of flow. All timing/counting circuits use crystal-controlled frequency references to eliminate any drift in the processing circuitry.
