NEW RELEASE! PORTABLE PRESSURE/FLOW DATA LOGGER ENGINEERED FOR EXTREME CONDITIONS — WATERPROOF AND SUBMERSIBLE WITH LONG-LIFE BATTERY POWER.
The completely updated PFL1 range of data loggers is based on the field-proven design of the PTRI/TRI model and utilize our patented data logging architecture that allows the user to monitor pressure/flow inputs in a multitude of configurations providing ultimate flexibility to meet specific application requirements.
The GCRTech PFL1 stores data in non-volatile memory organized into data files. Each data file is an independent data logger with its own start/stop time, sample rate, and logging rate. More than one data file can record different types of data for the same input channel.
Different types of data include Average, Instantaneous, Minimum, Maximum, etc. The memory register size is designed to be ready to accommodate overflows associated with high pulse rates on Flow inputs.
Pressure measurement accuracy is optimized using multi-point calibration. Logged data can be re-calibrated before, during, or after the recording by recalibrating the pressure transducer to the logger.
Local communications via fast non-contact IrDA communications link (115,200 baud). The logger firmware can also be upgraded in the field via the IrDA communications link.

Applications / Use Cases
The PFL1 allows for high-resolution pressure logging investigation to assess the root cause of various pressure anomalies. Sparsely placed permanent pressure monitors can highlight an anomaly but often times will not pinpoint its exact location or cause of the issue; using lift and shift portable pressure monitors like the PFL1 can increase the resolution of the root cause investigation to help quickly find and correct the anomaly.
Should a water customer complain of low pressure in their home or business, a municipality/utility can use the PFL1 to quickly log & record pressures on various hydrants in the area and/or on the customers service connection. Pressure data can is quickly acquired from the ease of the PFL1’s installation, and can be used to assist in resolving the complaint. Additionally, if a user can confirm consistent pressure on the distribution side, the municipality/utility can rule the pressure loss to the customer’s property side plumbing system.
Typically used for service-based/engineering consultant-led temporary projects. The primary use of the PFL1 pressure logger is for leak detection, water balance baseline data collection, or temporal model calibration data in cases where the utility doesn’t warrant/can’t yet afford a permanent network of pressure monitors. This also serves as a great “trial/demo” opportunity for the municipality to highlight critical pressure points & build towards a more robust permanent installation base of pressure monitors.
Allows for short term monitoring of localized pressure within a specific pressure zone/at critical water users within the pressure zone (particularly in new construction areas). Reviewing the data captured by the PFL1 pressure loggers will ensure that the water utility minimum level of service for supply pressures is maintained across the entire pressure zone. The PFL1 can also be utilized to log and record pressures on either side of a closed pressure district boundary valve to ensure there is a pressure differential and that the pressure zone valve is effectively closed.
Increases a user’s visibility into pump start/stop times from outside the fence of the pumping station. This is done by installing the PFL1 pressure logger on a local appurtenance such as a fire hydrant located near the subject pumping station. The PFL1 can showcase when pumps kick on/off allowing the user to build an accurate pump timing network which can be adjusted accordingly to increasing overall system efficiency. By utilizing the min/max pressure surge monitoring features of the PFL1, pressure surge detection can be captured identifying the need for a more thorough monitoring study using advanced GCR TRID-T portable transient loggers.
This use case is geared towards water utilities which utilize temporary district metered areas (DMAs) to establish leakage levels and target leak detection activities. Monitoring the average zone pressure and critical zone pressure points within the temporary DMA using the PFL1 pressure logger is critical to assess and correct the minimum night flow readings & calibrate pressure to establish the true leakage volume levels. In addition, the flow monitoring feature of the PFL1 can be utilized to log pressure and flow at the temporary DMA supply point(s).
Use of the PFL1 to log pressure during commissioning of a new watermain during construction will assist with performance assessment during swabbing and hydrostatic pressure testing activities. It allows for confirmation of valve closures by monitoring pressure on either side of a valve during watermain construction activities. It can further ensure adequate pressure is maintained in a close vicinity to the construction area where a watermain section may be isolated.
For use during development approvals and building insurance classifications. Utilizing the PFL1 will improve the accuracy and record keeping of pressure/flow data during fire flow tests. The PFL1 can provide graphical data for use in NFPA fire flow rating of water systems. Additionally, it can track hydrant pressure during C-Factor testing to assist in the overall identification of the internal condition of watermains and for hydraulic model calibrations. By utilizing the PFL1 loggers during C-Factor testing, there is no need to conduct elevation levelling between test hydrants as the elevation difference can be calculated directly from the logged pressure information collected from the PFL1 installed on both C-Factor test hydrants.
