Overview

The ClariVUE™10 is an ISO 7027 compliant, submersible, side-scatter turbidity sensor. It outputs an SDI-12, digitally processed signal that all modern Campbell Scientific data loggers can measure. The side-scatter turbidity measurement can be used as a surrogate for suspended sediment concentration in aquatic ecosystems.

Technical Description

The ClariVUE™10 is an ISO 7027 compliant, side-scatter turbidity sensor. It returns data via SDI-12 to a data logger. Turbidity is a common surrogate measurement for suspended sediment concentration in aquatic systems. The ClariVUE™10 is designed to operate in fresh and saline environments. It will require regular maintenance to keep the optical window clean in high bio-fouling environments. The face of the sensor is made from copper to slow biological growth over the optical windows.

ClariVUE 10 Program Example (1 KB) 11-08-2021

This example CR1000X program uses the M1! SDI-12 command to retrieve 100 burst measurements from a ClariVUE 5 or ClariVUE 10. The sensor makes 100 measurements to calculate turbidity statistics (median, mean, standard deviation, minimum, maximum) and mean temperature.

Number of FAQs related to ClariVUE10: 2

  1. The most significant difference between backscatter and side-scatter measurements is the sample volume. A backscatter sensor has a much larger sample volume that helps measure higher turbidity values. The smaller sample volume of side-scatter sensors works better at lower turbidities.

  2. It used to be that NTUs were the unit for all turbidity sensors. In 2007, an ASTM committee formed and established different units for each category of turbidity sensor technology, and there are many. Backscatter sensors such as the OBS-3+ and the OBS501 have units of FBU (Formazin Backscatter Units), whereas ISO 7027 side-scatter sensors have units of FNU (Formazin Nephelometric Units). The side-scatter OBS501 and the ClariiVUE™ sensors are part of this category. While sensors of different technical designs can be calibrated and measure Formazin the same, they will not make the same measurement in natural waters where size, shape, color, reflectivity, etc., of the particles vary. The ClariiVUE™ sensor measurements will not match the OBS-3+ measurements in natural waters.
