Maximum Operating Pressure
High-performance vortex flowmeter with robust
sensor for highly accurate volume or mass flow
measurements of gasses, liquids, saturated and
superheated steam.
1. DSC (Differential Switched Capacitance)
sensor
offers a wide measuring range, with a high
resistance to thermal shock, vibration and water
hammer.
2. Integrated flow computer calculates mass flow from
measured volume flow and temperature variables.
3. Capable of simultaneous pulse (interval) and
analog (instantaneous) output.
4. Requires no maintenance, has no moving parts,
and experiences no zero point drift.
5. Low pressure drop through body.
