Resumen

The CRS451 consists of a water-level and water-temperature sensor that has its own time clock and memory to store the collected data, in a compact stainless-steel case. This frees users to place the sensor in remote sites and let it collect data for long periods. The sensor can then be retrieved, connected to a PC via a micro-USB port, and the data transferred to the PC. HydroSci software is included and elegantly supports test setup, data retrieval, and data display. Long battery life and rugged construction mean you can trust the CRS451 to collect important data. Low cost and ease of use make it a good choice in a variety of applications.

Descripción detallada

The CRS451 has several pressure range options. The CRS451 is unvented; therefore it is monitoring sealed gage pressure. For maximum accuracy, the data should be corrected for barometric pressure. 

HydroSci software is included in the Resource DVD. This software simplifies the process of configuring the CRS451. Users can configure the CRS451 to monitor surface water, ground water, or a standard pump test.

HydroSci software will also compensate the measurements for barometric pressure using an additional CS451 or a CS456 as a reference sensor, or using a barometric pressure sensor from a nearby weather station.

HydroSci software will display the data in tabular or graphical formats.

Preguntas frecuentes

Número de FAQs relacionadas con CRS451: 1

  1. What is the nature of the reference pressure?

    The CRS451 and CRS456 are unvented and monitor sealed gage pressure. For maximum accuracy, the data should be corrected for barometric pressure. The barometric pressure data from a nearby weather station or other monitoring platform can be used.
