Custom Flow Meters

As a specialist in custom engineering solutions, DDM Sensors offers you custom flow meters tailored exactly to your specific application. We implement modifications and new developments across diverse measurement principles, ready for deployment within a few weeks. Furthermore, we develop custom flow meters starting from a minimum order quantity of just one unit.

Properties of DDM Sensors Flow Meters

Our flow meters are suitable for ultra-low flow rates starting at 0.002 L/min up to high-capacity volumes of 1,200 L/min. Additionally, our sensors are designed for operation in high temperature ranges, from a minimum of -40 °C up to +150 °C. Extended temperature ranges are available upon request.

Development of Flow Meters

To realize your unique metrological requirements, we follow two fundamental engineering approaches: we offer both the modification of our proven, existing stock flow meters as well as the complete turnkey development of a new flow meter according to your specifications.

Modification of Our Existing Flow Meters

An efficient path to your custom solution is the modification of flow meters from our current portfolio. Here, we selectively adapt various specifications such as mechanical connections, electronic interfaces, or measuring ranges.

New Development of Flow Meters

If required, we also develop completely new flow meters from scratch. To keep the development phase short and maximize reliability, we preferentially rely on existing, proven measurement principles that can be further enhanced.

Development Process for Custom Flow Meter Solutions

Delivery times for custom-built designs depend on the project scope and can vary from a few weeks to several months. Our flow meter development process is divided into 6 distinct steps:

• Step 1: Technical analysis of your requirements and specifications
• Step 2: Selection of the appropriate measurement principle
• Step 3: Concept development
• Step 4: Design and engineering
• Step 5: Prototype manufacturing and validation
• Step 6: Series production of the final flow meter You are fully involved in every step of the process, ensuring transparent insight into the development progress of your specific flow meter at any time.

Custom Solutions for Diverse Measurement Principles

We engineer custom solutions based on a wide range of established measurement principles:

• Turbine flow meters
• Oval gear flow meters
• Ultrasonic flow meters
• Paddlewheel flow meters
• Electromagnetic inductive flow meters

Overview of Customization Options

Mechanical Customizations

Mechanical modification options include various housing materials such as stainless steel, plastics, or specialty alloys, as well as a large selection of process connections, including threads, flanges, and clamp connections. We also implement custom electrical connections (connectors, cable configurations), compact designs for confined installation spaces, and use chemical-resistant sealing materials like FKM, FFKM, or EPDM depending on the medium.

Furthermore, we adapt our flow meters to individual process pressures and design them for extended temperature ranges, such as extreme operating conditions from -200 °C to +200 °C. We also carefully evaluate media compatibility—particularly when handling aggressive media—to ensure reliable resistance and a long service life under demanding operating conditions.

Electronic Integration

We implement analog output signals like 4–20 mA or 0–10 V, as well as digital communication protocols such as Modbus, Profinet, or EtherCAT. Upon request, we integrate local displays for configuration and real-time measurement readings, or perform customer-specific firmware adaptations.

Measuring Range Specifications

The sensor’s performance parameters are matched exactly to your process requirements. This includes defining the measuring range, which can span from a few milliliters per minute up to cubic meters per minute. In addition, we specify the pressure rating, temperature resistance, accuracy class, and response times precisely tailored to your application.

Is There a Minimum Order Quantity?

We manufacture flow meters starting from a batch size of just a single unit. Our production processes are specialized for annual volumes under 10,000 units, allowing us to guarantee high flexibility for prototyping as well as small and medium series runs.
