Two new ultrasonic steam flowmeters from Panametrics, the DigitalFlow GS868 and XGS868, solve pressure drop and rangeability problems found in other flowmeters the company reports. This helps reduce operation, installation and maintenance costs. The GS868 is a full featured flowmeter, while the XGS868 is a lower cost flow transmitter. Using Correlation Transit-Time Technology, the meters do not obstruct the line, so full steam power is always delivered. They measure mass flow rate of saturated and superheated steam over a wide range.

More deliverable steam with less maintenance
When measuring steam flow rate, the pressure drop caused by flowmeters such as orifice plates and vortex shedding absorbs energy from the steam, reducing the amount of power and heat delivered to the user. The GS 868 and XGS868 cause no pressure drop and reduce steam generation costs. No regular maintenance is required, further reducing the long term cost of ownership the company reports. The flowmeters have two titanium transducers with an all metal boundary and are not affected by erosion from droplets. Failure due to thermal expansion cycles is eliminated reports Panametrics.

Wide range
A single GS868 or XGS868 ultrasonic flowmeter can cover a wide range of flows, giving additional savings. Because of their limited turn down ratios, conventional meters are used in multiple runs to cover all steam flow rates during high and low demand periods. A single GS868 or XGS868 covers the full range resulting in reduced capital and installation costs.
The GS868 and XGS868 can be used with wet, saturated or superheated steam. Turn down ratio is 150 to 1. Maximum temperature is 260 degrees Celsius using regular Panametrics transducers. Higher temperatures up to 450 degrees Celsius are possible using the company's Bundle Waveguide Technology system transducers. Pipe sizes can range from 50mm (2 inches) to 122cm (48 inches) with pressures ranges from 0 to 103bar.
