Versatility in Variable Area Flow Measurement

The H250 M40 variable area (VA) flowmeter is a cornerstone of the process and OEM industries, representing the perfect synergy of classic mechanical measurement and cutting-edge digital communication. Its simple, low-cost design allows it to provide accurate flow readings for both liquids and gases without the need for an auxiliary power supply, making it incredibly reliable in the field. This foundational mechanical functionality is supported by a unique modular design, which allows for the seamless addition or replacement of electronic modules. This means the H250 M40 can adapt to new requirements at any time, from a basic mechanical indicator to a fully integrated digital device within a modern fieldbus system. Its adaptability and robust build, featuring various stainless steel and alloy sensor materials, ensure it stands up to the most demanding industrial environments, proving that simplicity and sophistication can indeed coexist.

Unmatched Adaptability and Universal Functionality

The H250 M40’s unparalleled modularity and universal functionality make it an exceptionally versatile instrument. Its ability to be installed in any position—vertical, horizontal, or even in descending pipes—gives it a significant edge over conventional flowmeters. The meter is equipped with a wide range of connection options, including flanges (DN15-150 / ½-6″), threads (NPT, G), and various hygienic connections, making it compatible with virtually any piping system. This flexibility is a key advantage for Original Equipment Manufacturers (OEMs) and for retrofitting existing plants. The H250 M40’s functionality can be easily extended with optional modules like limit switches, a 4-20 mA output, a totalizer with an LCD and pulse output, or a fieldbus interface (HART®7, FF, Profibus-PA). This on-demand adaptability ensures that the H250 M40 remains relevant and efficient for a variety of applications, from the simplest flow indication to complex process automation.

A Focus on Safety and Operational Integrity

Safety is a critical concern in process industries, and the H250 M40 is designed with this in mind. The meter is suitable for use in Safety Instrumented Systems (SIS) with a SIL 2 rating, and in redundant designs (1oo2), it is even approved for SIL 3 applications. This makes it a dependable choice for managing critical processes where safety is paramount. The device’s robust design also includes a universal Ex-concept, providing both explosion-proof and intrinsically safe options for hazardous areas. The meter’s advanced diagnostics, powered by NE 107, include Continuous Float Monitoring (CFM), which can detect and alert operators to float blockages, a common issue in VA meters. This early detection capability helps prevent process failures and ensures measurement integrity. With its ingress protection ratings of IP66, IP68, and NEMA 4X/6, the H250 M40 is also a reliable choice for use in harsh, corrosive atmospheres.

Specific Applications Across Diverse Industries

The H250 M40 is a true workhorse, excelling in a wide array of specific applications across various industrial sectors:

• Chemical and Petrochemical Plants: It is used for dosing and batching of chemicals, where its accuracy and low-cost installation are significant advantages. It’s also suitable for monitoring the flow of gases in reactors or lubricants in industrial machinery.
• Food and Pharmaceutical Industry: With its optional hygienic design, the H250 M40 is perfect for measuring liquids and gases in sanitary applications, such as CIP (Cleaning-in-Place) systems or the dosing of ingredients.
• Water and Wastewater Treatment: The meter can be used to measure the flow of chemicals like chlorine or flocculants, which are essential for treating water and ensuring it is safe for consumption.
• Oil and Gas: Its high-pressure capability (up to 1000 barg / 14500 psig) makes it suitable for monitoring injection fluids or gases in upstream operations.
• General Industrial Processes: The H250 M40 is the standard for countless OEM applications, where it is integrated into a wide range of equipment for flow control and measurement. Its ability to measure both liquids and gases with a turndown ratio of 10:1 (and an optional 100:1) makes it incredibly versatile for general process automation.

Robustness for Extreme Temperatures and Pressures

The H250 M40 is built to withstand extreme operating conditions. Its construction allows it to handle process temperatures from -196°C to +400°C (-320°F to +752°F) and process pressures up to a staggering 1000 barg (14500 psig). This impressive range makes it a reliable choice for a diverse set of applications, from cryogenic liquids to superheated steam and high-pressure gases. The availability of a variety of corrosion-resistant materials, including Hastelloy®, Monel®, and Titanium, ensures that the H250 M40 can withstand corrosive media, enhancing its durability and operational life. This combination of robust design and material options ensures that the H250 M40 is not just a flowmeter but a dependable component of a facility’s critical infrastructure.

Effortless Installation and Low-Cost Operation

The H250 M40 is designed for simplicity and cost-effectiveness from the ground up. Its ability to provide flow measurement and a local display without any external power supply is a huge advantage, especially for remote or off-grid installations. The meter’s maximum measuring error of ±1.6% of the full scale (according to VDI/VDE 3513-2) or ±1.5% of the full scale provides excellent accuracy for most industrial needs. The modular design, which allows for additional functionality to be added at a later stage, ensures that the initial investment remains low. This is particularly beneficial for projects that may have evolving requirements or for companies seeking to standardize their flow measurement solutions. The H250 M40 proves that high quality and advanced functionality do not have to come with a high price tag or complex installation procedures.
