CRS451/CRS456 Submersible
Water-Level Recording Sensor
1. Introduction
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 of time. The CRS451/CRS456 supports standard time-based
scanning and recording along with event-based recording based on water level
change (Delta) or logarithmic time sequence for pump and slug tests. HydroSci
software is included and supports test set up, data retrieval, and data display.
The CRS451 has a 316L stainless-steel case that can be submerged in most canals,
wells, ponds, lakes, and streams. The CRS456 has a rugged titanium case that
allows it to be used in saltwater or other harsh environments.

2. Cautionary Statements

The CRS451/CRS456 will be damaged if encased in frozen liquid (see
Section 6.2,
Avoiding Freezing Conditions , for more information).

Although the CRS451/CRS456 is a rugged and reliable device, it is also a
highly precise scientific instrument and should be handled as such.

Dropping the instrument or allowing it to “free fall” down a well may damage
the transducer.

Confirm the compatibility of the instrument to non-water environments before
installation.

The CRS456 should be used in harsh water applications, including salt water.
3. Initial Inspection and Handling Guidelines

Upon receipt of the CRS451/CRS456, inspect the packaging for any signs of
shipping damage. File damage claims with the shipping company.

Immediately check package contents against the shipping documentation (see
Section 3.1,
Ships With ). Contact Campbell Scientific with any discrepancies.

The model number and pressure range are etched on the housing.
Check this information against the shipping documentation to
ensure that the expected product was received.
