Multiple input pressure/flow data logger with cellular connectivity — waterproof and submersible with long-life battery power available in a variety of configurations — highly flexible and ready to satisfy the most challenging site conditions.
The PFM1 data logger has up to 8 data files for monitoring a range of analogue and digital signals and benefits from the latest advances in cellular communication.
These advanced devices utilize a unique data logging architecture that can detect pressure surges and measure minimum night flow more accurately using Pulse Interval Timing [PIT]. The loggers allow users to analyze data in greater detail than currently available with traditional loggers. These powerful features enable additional fast logging, such as step testing, without interfering with the main 15-minute recordings.
PFM1 data loggers store data in non-volatile memory organized into data files. Each data file is an independent data logger with its own logging parameters. 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.
Communications via 4G/5G LTE CAT M1 and NBIoT cellular options deliver industry-leading backhaul connectivity while still offering 2G options for legacy systems.
