For Measuring Low Flowrates, Consider this Device

The mini CORI-Flow Series (photo) is a compact and cost-effective Coriolis mass flowmeter and controller for accurate measurement and control of very low flowrates from 100 mg/h up to 30 kg/h. The Coriolis sensor is said to feature superior response time and high accuracy, regardless of changing operating conditions (pressure, temperature, density, conductivity and viscosity). Suitable for both liquid- and gas-flow applications and capable of bi-directional measurement, the devices are equipped with IP 65 weatherproof housing and are available with approvals for use in hazardous areas (ATEX Cat. 3, Zone 2). — Bronkhorst Cori-Tech B.V., Ruurlo, The Netherlands
