Valmet Conductivity Measurement (3100-series)

Valmet inline conductivity measurements

Valmet offers accurate and durable in-line conductivity measurements. Valmet's conductivity meters are based on 4-electrode technology developed by Kemotron A/S in the 1960s. Thanks to unique sensor head design they are resistant to scaling, which means superior accuracy with minimum maintenance. The cell constant is stored in the conductivity meter, which is recognized automatically by the transmitter.

The conductivity meters are interchangeable and do not need recalibration or re-entering of the cell constant when switching to a new unit. Valmet offers a broad selection of conductivity meters for heavy industries as well as sanitary applications in pharmaceutical plants and dairies. Valmet conductivity meters have a typical lifetime of more than 10 years, even in the most demanding applications. Some conductivity meters have worked since the 1980s and still continue to measure at good accuracy.

The single-channel transmitter has two 4-20 mA-outputs and four individually selectable set-up modes, two for Ultrapure Water (UPW)/Water for Injection (WFI) and two for high conductivities. Each of the four set-up modes has an individual setting of up to 13 different temperature compensation for different applications. Mounting to wall, panel or pipe is available with power options for either line- (85-265 VAC) or loop-power (18-30 V). HART® protocol for field device transmitters is implemented as standard.
