Variable Area Flowmeters

Variable area flowmeters are the low-cost solution for almost all applications involving the measurement of industrial process liquids, gases or steam. Usually, the challenge is to find a cost-effective but reliable measurement solution. In order to quickly determine the status directly in the field is to sometimes use an easy-to-install and highly robust local flow indicator. A wide range of variable area flowmeters that require no special installation conditions is the solution. Providing a cost-effective solution for measuring moderate to very low flow rates, they include metal, glass and purge flowmeters suitable for nearly any application and installation requirement. The flowmeter can be used as pure indicators without the need for a power supply or can transmit process information via contact output or current 4/20 mA to a process control system.
