About Fluid.iO / MARIMEX
Fluid.iO Sensor + Control GmbH & Co. KG manufactures inline process viscometers of the ViscoScope product family under the MARIMEX brand, including the VA-100, VA-300, VA-31F, VA-11F types and the VS-x450 series (e.g. VS-4450). The modular measuring systems are used for continuous viscosity measurement in pipelines and reactors and are made in Germany. Fields of application include the process industry, in particular synthetic resin and resin production for paints, impregnations, adhesives, coatings and mortar additives, as well as the food and brewing industry (EHEDG hygienic design) and explosion protection applications (Ex i). In addition to the measuring instruments, the company offers consulting on installation, evaluation of measurement data, support, maintenance and service including decontamination procedures as well as the ViscoView and VisConfig software. Marimex America LLC emerged from Marimex Industries GmbH & Co. KG, founded in 1996 in Bottrop, together with the US partner West Machine Works; as of 01.01.2023 the business divisions were merged under Fluid.iO Sensor + Control with headquarters in Bensheim.
