Optisonic 8300 Flowmeter
Description
With the OPTISONIC 8300, KROHNE presents a dedicated ultrasonic flowmeter for the measurement of superheated steam. The 2-beam flowmeter stands out with a measuring accuracy of 1%, high repeatability, and a large dynamic measuring range. Typical applications include boiler and plant efficiency monitoring in (power) plants, energy balancing or inter-company steam billing.
As downtime of steam pipes is very costly and must be avoided, OPTISONIC 8300 was built for long-term use: 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. Therefore, it can uphold its measuring accuracy without maintenance or subsequent calibration for up to 20 years, while keeping operating costs at a minimum. If verification of the measuring accuracy should become necessary, it can be provided by using the flowmeter diagnostics, without removing the flowmeter.
With nominal sizes ranging from DN 100 to 1,000 / 4 to 40 in., OPTISONIC 8300 is particularly suited to high flow rates. Pressure ratings up to 200 bar/3,625 psi and temperature ratings up to 1,004°F (540°C) are available, with higher requirements on request. With temperature and pressure sensors connected to the device, the integrated flow computer can calculate steam mass flow.
