Portable Field Calibration Devices (FCDs)


The Field Calibration Device (FCD) effectively enables field technicians to calibrate any given rain gauge thereby saving time and money. The advantage of using a Field Calibration Device is that the Tipping Bucket Rain gauges can remain fixed in their location and are therefore only out of service for a very short period of time.

A pre-set volume of water will discharge through the Tipping Bucket Rain Gauge. This process is to be repeated a second time for an accurate calibration check. The number of tips can be manually counted or stored on the data logger for calibration check evidence and then checked with ‘‘Calibration Specifications’’ to confirm that the results come within the acceptable range.
