The KROHNE H250-RR sets a new standard in variable area flow meter technology. Combining a rugged, all-metal design with numerous display, communication and other options, the H250-RR is a reliable and versatile instrument ideal for measuring the flow of conductive and non-conducting liquids and gases in difficult applications and extreme environmental conditions.
The KROHNE H250-RR variable area flow meter is available in sizes from 1/2" to 4" with corresponding flow rates ranging from as low as 0.47 gph (0.026 scfm for gases) to as high 26,418 gph (1736 scfm). The basic accuracy for flow readings is an excellent ±1.6%. Due to its sturdy, all-metal construction, the H250-RR ensures high resistance to pressure, temperature and media. The modular design of the meter and indicator allows users to adapt the H250-RR to customer-specific applications including those in hazardous areas.
KROHNE H250-RR variable area flow meters operates of the float principle. Depending on the flow rate, the float will assume a certain vertical position in the tube. The float position is transmitted by a magnetic coupling system to the scale. This simple, time-tested design will ease installation time and lower maintenance demands.
The KROHNE H250-RR variable area flowmeter is available with the following indicator options:
This product can be used in the following applications:
The Background: Our customer is an industrial facility that requires a means of monitoring the flow rate of high pressure helium used in plasma spraying applications.
The Problem: The sensing technologies of many types of flow meters are unable to accurately measure the flow of high pressure gases.
The Solution: We recommended the Krohne H250-RR variable area flow meter which has a rugged, all metal construction of the tube, with no ports or taps, which allows metering of very high temperature and high pressure fluids. Properly configured the H250-RR can meter fluids over 570°F or 5800PSI.
