The Krohne H250-F variable area flow meter is an all-metal instrument designed specifically for the food and pharmaceutical industries. Combining sanitary design elements with numerous display, communication and other options, the H250-F is a reliable and versatile instrument ideal for measuring the flow of liquids, gases and saturated steam in hygienic applications.
Krohne H250-F variable area flow meters are available in sizes from 1/2" to 2" with corresponding flow rates ranging from as low as 0.47 gph (0.026 scfm for gases) to as high 4227 gph (217 scfm). The basic accuracy for flow readings is an excellent ±1.6%. Due to its sturdy, all-metal construction, the H250-F ensures high resistance to pressure, temperature and media. The modular design of the meter and indicator allows users to adapt the H250-F to customer-specific applications including those in hazardous areas.
The Krohne H250-F variable area flowmeter is EHEDG-certified and features smooth stainless steel surfaces. Parts in contact with the medium have a surface roughness of less than 0.8 µm, making it difficult for deposits to stick as well as easy to clean. Combined with a design devoid of dead spaces and stagnation zones, microorganisms cannot stick and multiply. The H250-F can be cleaned (CIP) and sterilized (SIP) while intact. The meter is available with suitable connections and FDA conforming materials for the food and pharmaceutical industries.
The Krohne H250-F variable area flow meter is available with the following indicator options:
