Labcal offers flow meters designed specifically for a range of air flow options which are verified at 1013 mbar (absolute) at 20˚C.
The Series 1200 Variable Area Flow Meters utilise a simple method of measuring flow rate whereby the position of the float within the tapered glass tube achieves equilibrium for a particular flow rate. They have exceptional resolution due to a 300 mm nominal tube length and excellent measurement repeatability and reliability.
