Thiết bị đo lưu lượng hơi bằng siêu âm Digital Flow GS868

Mô tả sản phẩm

The DigitalFlow™ GS868 and XGS868i ultrasonic steam flowmeters solve the problems of pressure drop and rangeability found in other flowmeters by reducing operation, installation and maintenance costs. Our line of steam flow meters are full-featured meter that measure mass flow rate of saturated and superheated steam over a very wide range of pipe sizes and flow conditions.

When measuring steam flow rate, pressure drop caused by orifice or vortex shedding meters robs energy from the steam, reducing the amount of power and heat delivered to the user. Using the GS868 or XGS868i with two ultrasonic transducers that do not protrude into the flow stream, transducer installation is obstructionless, causing no pressure drop and reducing steam generation costs. No regular maintenance is required with the new flowmeters, further reducing long-term cost of ownership. Their titanium transducers have an all-metal boundary and are not affected by erosion from droplets. They will not fail due to thermal expansion cycles.

A single GS868 ultrasonic flowmeter can cover a wide range of flows, giving additional savings. Because of their limited turndown ratios, conventional meters are used in multiple runs to cover all steam flow rates during high and low demand periods. Using a single GS868 flowmeter to cover the full range can result in lower capital and installation costs.
