A flow calibrator - and so much more!

Aug 25 2021

The CF1 from Dado Lab is no ordinary flow calibrator. Not only does it measure actual and normalised flow rates, it also measures the volume passing through the cell, ambient pressure, gas temperature and pressured drop of line. The CF1-UR model also measures ambient temperature and relative humidity.

This device features an annular laminar flow cell which enables a flow rate range with a very wide dynamic 1:100 (from 0,45 to 45 l/min) and the capability to measure flows both sampled or delivered by the pump. The CF1 is compact and light, weighing only 300 grammes, and is equipped with LiPO batteries which makes it ideal for use as a secondary reference for field operations.

All CF1 sensors can be ISO17025 certified, which also makes them suitable as the primary laboratory reference for flowrate, volume, pressure, temperature and rH%. CF1 also features wireless communication capabilities, it comes supplied with a USB dongle for direct communication of all the readings via the software (under development) for long lasting sampler tests. The software will also allow users to program the certificates into the unit. A high accuracy calibration is available as an option to deliver the unit with a flowrate accuracy of 0,8% ± 0,1% f.s.!
