Maximum Operating Pressure

High-performance vortex flowmeter with robustsensor for highly accurate volume or mass flowmeasurements of gasses, liquids, saturated andsuperheated steam.

1. DSC (Differential Switched Capacitance) sensoroffers a wide measuring range, with a highresistance to thermal shock, vibration and waterhammer.

2. Integrated flow computer calculates mass flow frommeasured volume flow and temperature variables.

3. Capable of simultaneous pulse (interval) andanalog (instantaneous) output.

4. Requires no maintenance, has no moving parts,and experiences no zero point drift.

5. Low pressure drop through body.

There is no restriction for mounting position (A – D) in regards to meter accuracy. However, special care is recommended for the following flow mediums:

1. High-temperature FluidsFor high-temperature fluids (steam, condensate), positions A, B or C should be selected to protect the transmitter form heat.

2. LiquidsTo make sure the pipes are completely flooded with liquid, position C is recommended.

The pipe stand serves as a radiator and protects the electronics from overheating. Therefore, ensure that sufficient surface area remains exposed.Be sure not to insulate past the level marked “max.” on the pipe stand.

Wet steam has a higher density than saturated steam.Since the flowmeter mass flow calculations are based on saturated steam density, the actual mass flow of wet steam will be higher than shown by the flowmeter. The upstream installation of a separator (DC3S) is suggested to ensure steam quality and flowmeter accuracy.The proper separation and drainage of condensate is a recommended practice for all steam applications.
