Mobiltex GCRTech - Model PFM1-T -Transient Pressure/Flow Data Logger Engineered for Extreme Conditions

Two data loggers in one! Capture pressure average and surge data in separate files — waterproof and submersible with long-life battery power and unique features that field technicians demand.

Pressure surges are logged and surge data plus the slow logged data is sent via cellular communication for the cellular enabled PRM1-T model or downloaded manually using the USB to IrDA communications cable for the non-cellular enabled model.

If external power is connected the logger can sample pressure at 1KHz continuously, detect and record data at 10Hz, 20Hz, 100Hz or 1KHz before during and after the surge event.

• With a variety of pressure & flow port configurations, the PFM1 can independently log pressure or flow data while further having the ability to log both parameters at the same time.
• The PFM1 is the highest-resolution pressure surge logger on the market, capable of taking up to 1,000 readings per second during a transient event.
• Adjustable pressure & flow data sampling rates to fit every job. Sampling rate: 1 second to 15 minutes; Standard Logging rate: 5 seconds [portable]/1 minute [cellular] to 24 hours
• Gives users the choice to simultaneously or independently log a wide selection of data types, including maximum, minimum and average pressure.
• Operating on a variety of cellular bands (2G, 4G/5G LTE CAT M1 or ), the PFM1 can transmit data from virtually any location with cell coverage. This helps improve the quality & frequency of data collection while also reducing the need for field staff to undertake time consuming, potentially dangerous field trips.
• The PFM1 is available as either a non-communicating, portable unit or a fully telemetric cellular comms unit. Additionally, portable units can be field-upgraded to cellular on the fly.
• Cycles through logger parameters to provide at-a-glance information to users without the need to connect to a computer
• Meticulously designed to withstand the harshest environments (-20 to 70 degrees C, -5 to 160 degrees F)
• The PFM1 will continue to operate even when completely submerged in water or when exposed to dusty/dirty/sandy environment
• Field-replaceable batteries with 5+ years of life under normal operating conditions
• The addition of 8 separate data files ensures that any data transmitted from the field is further backed up on the internal PFM1 memory
