About this manual

Please note that this manual was originally produced by Campbell Scientific Inc. primarily for the

North American market. Some spellings, weights and measures may reflect this origin.

Some useful conversion factors:

Area: 1 in2(square inch) = 645 mm2

Length: 1 in. (inch) = 25.4 mm

1 ft (foot) = 304.8 mm

1 yard = 0.914 m

1 mile = 1.609 km

Mass: 1 oz. (ounce) = 28.35 g

1 lb (pound weight) = 0.454 kg

Pressure: 1 psi (lb/in2) = 68.95 mb

Volume: 1 UK pint = 568.3 ml

1 UK gallon = 4.546 litres

1 US gallon = 3.785 litres

In addition, while most of the information in the manual is correct for all countries, certain information

is specific to the North American market and so may not be applicable to European users.

Differences include the U.S standard external power supply details where some information (for

example the AC transformer input voltage) will not be applicable for British/European use. Please

note, however, that when a power supply adapter is ordered it will be suitable for use in your country.

Reference to some radio transmitters, digital cell phones and aerials may also not be applicable

according to your locality.

Some brackets, shields and enclosure options, including wiring, are not sold as standard items in the

European market; in some cases alternatives are offered. Details of the alternatives will be covered in

separate manuals.

Part numbers prefixed with a “#” symbol are special order parts for use with non-EU variants or for

special installations. Please quote the full part number with the # when ordering.

Recycling information

At the end of this product’s life it should not be put in commercial or domestic refuse

but sent for recycling. Any batteries contained within the product or used during the

products life should be removed from the product and also be sent to an appropriate

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.

Before using the CRS451/CRS456, please study:

Section 2, Cautionary Statements

Section 3, Initial Inspection

Section 6, Installation

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.

CRS451/CRS456 Submersible Water-Level Recording Sensor

3.1 Ships With

#27555 USB 2.0 Cable Type A Male to Micro B Male, 6ft

#29225 HydroSci Software on CD

4. Overview

The CRS451/CRS456, Submersible Water-Level Recording Sensor, provides

reliable, accurate pressure/level measurements that are fully temperature

compensated.

The 24 bit A/D has simultaneous 50/60 Hz rejection and automatic calibration for

each measurement. A number of additional advanced measurement techniques are

employed to harness the best possible performance available from today’s state of

the art pressure sensor technology. The CRS451/CRS456 reverts to a low power

sleep state between measurements. A series of measurements are performed

yielding a temperature and pressure value. This measurement cycle can be as fast

as 1 second.

The design features a piezoresistive sensor housed in a 316L stainless steel

(CRS451) or titanium (CRS456) package to enhance reliability. The rugged

construction makes the CRS451/CRS456 suitable for water level measurement in

irrigation applications, water wells, lakes, streams, and tanks. The titanium

package of the CRS456 makes it ideal for salt water or other harsh environments.

The CRS451/CRS456 has three nose cone options. The weighted nose cone

makes the transducer easier to submerge to depth. The NPT option allows the

sensor to be mounted to a 1/4 inch fitting. The nose cones can be exchanged at a

later time.

Communicating with the CRS451/CRS456 requires a micro USB cable and

HydroSci software running on a computer with Windows XP or later.

Configurable settings can be changed using Campbell Scientific’s HydroSci

software utility.
