Sampling systems - Import export

Clean water is essential for life. As more chemicals are introduced to the environment, adverse consequences to water quality and corresponding health impacts will increase as well. In order to provide the highest level of safety and security, a fast response to water quality issues is necessary. The CMS5000 is a GC-based system that autonomously samples VOCs in water, quantifies contaminant levels and automatically alerts users if thresholds are exceeded.

The DK46/47/48/800 is a variable area (VA) flowmeter for monitoring and adjusting extremely small flow rates of liquids and gases. It is thus particularly useful for sample flow monitoring in analyser systems and gas chromatographs or measuring liquids and gases in laboratories and pilot installations. The purgemeter operates without auxiliary power supply and is available with different glass tube and installation lengths from 90 to 325 mm / 3.55 to 12.8". The medium is visible and the flow value can be read directly off the scale at the height of the float. The glass flowmeter can be provided with max. two limit switches (NAMUR) or a 3-wire digital output. For precise setting of the flow value, the VA meter features a needle valve. The DK 46/47/48/800 is also available with a differential pressure/flow regulator to provide constant flow rates in case of varying inlet or outlet pressures. The device has approvals for use in hazardous areas.
