Additional Equipment

Explosion-protected Containers

Whenever measurements have to be conducted in areas with potentially explosion-hazardous atmosphere, the instruments can safely be set up in explosion-proof containers.

Certified for ATEX zone 1 and 2.

Feeding Pumps

Filter Unit with fine Strainer

Flat Filter System

Flat filter system

Installed ahead of analysers if finest dirt needs to be filtered off before measurement, as it is common practice in the phosphate measurement.

Includes a powerful pump and a wear monitoring gauge; no additional compressor is required. The filter insert is replaceable and exhibits long service life without the use of chemicals for cleaning.

Optionally available with filtrate heating.

Flow Cells for Measurement Probes

Flow cells for measurement probes

If the sample is easily accessible for measurement, e.g. in a basin or open flume, the probes can simple be immersed for measurement. Probes which don’t meet the requirements of IP68 are mounted in an IP68 protective armature instead, which protects the sensitive electronic parts during prolonged immersion.

The tip of the protective armature has a special shape in order to serve as vortex funnel, ensuring an optimum flow around the probe.

Flow cells

Measuring Weirs

Measuring weirs are used for flow measurement.

The measuring weir introduces a constriction into a channel, and the water flows over the crest of the weir. This creates defined conditions, which allow accurate determination of the flow rate by measurement of the height of the water above the crest (head over the weir).

The head over the weir is usually measured with pressure or ultrasonic sensors.
