Krohne has introduced the Optisonic 8300 ultrasonic flowmeter for superheated steam, which delivers 1% measuring accuracy, high repeatability, and a large dynamic measuring range with maintenance-free operation.
The two-beam ultrasonic flowmeter is capable of handling high flow rates of superheated steam, making it well-suited for power plant boiler and plant efficiency monitoring, energy balancing, and inter-company steam billing.
As downtime of steam pipes is very costly, the Optisonic 8300 was built for long term use and it features a full bore flow sensor without moving parts or obstructions and an overall sturdy and robust construction with no cables or sensitive parts exposed.
The highly accurate flowmeter can maintain its measuring accuracy without maintenance or subsequent calibration for up to 20 years, while keeping operating costs at a minimum.
Verification of the measuring accuracy can be achieved by using the flowmeter diagnostics without removing the flowmeter itself, reducing the need for costly downtime.
The Optisonic 8300 is available in nominal sizes ranging from DN 100...1000 / 4…40" and is particularly suited to high flow rates.
The flowmeter is rated for pressure up to 200 bar and temperature up to 540°C, with higher rated units available on request.
Temperature and pressure sensors connected to the device provide the integrated flow computer with data to calculate steam mass flow, eliminating the need for an additional flow computer.
The flowmeter’s wide measurement eliminates the need for a dual range measurement setup, simplifying installation, operation, and maintenance.
