Rossonix Co., Limited, a trusted global trading company established in 2011 with annual export value exceeding US$5 million, is proud to present the JM Durchflussmesstechnik B5040 Positive Displacement Rotary Vane Flow Meter. This volumetric flow measuring device is engineered for precise, reliable measurement of low to medium viscosity liquids, including water, oils, fuels, and chemicals. With its robust design and proven positive displacement technology, the B5040 offers exceptional accuracy and repeatability, making it an ideal choice for industrial process control, hydraulic systems, and fluid transfer applications.
As a dedicated supplier with overseas offices and a broad network covering North America, Europe, Asia, and Oceania, Rossonix ensures that every B5040 flow meter meets the highest quality standards. Our ISO 9001:2015 certified facility and strict quality control procedures guarantee that you receive a product that performs consistently in the most demanding environments. Whether you need to monitor fuel consumption, dose chemicals, or manage hydraulic oil flow, the B5040 delivers the accuracy and durability you require.
The B5040 operates on the positive displacement principle using a precision-machined rotary vane mechanism. As fluid passes through the meter, the vanes rotate, and each revolution corresponds to a fixed volume of fluid. This design ensures that the meter is highly accurate across a wide flow range, with minimal pressure drop. The meter's robust construction, available in aluminum or stainless steel, provides excellent corrosion resistance and long service life.
Key Features & Technical Specifications
- High Accuracy: ±0.5% of reading (typical) for reliable process control.
- Wide Flow Range: Models available from 0.5 to 120 L/min, covering diverse applications.
- Low Pressure Drop: Minimal resistance ensures efficient system operation.
- Versatile Material Options: Aluminum body with stainless steel internals or full stainless steel construction for corrosive fluids.
- Multiple Outputs: Pulse, reed switch, or Hall effect sensor for easy integration with controllers, PLCs, or displays.
- Easy Installation: Threaded connections (G1/2, G3/4, etc.) and compact design for space-saving mounting.
- Durable Construction: Designed for long-term reliability in harsh industrial environments.
- No External Power Required: Mechanical flow meter operates without electricity in standard versions.

| Connection | G1/2, G3/4, G1 female threads |
| Output Signal | Pulse (NPN/PNP), Reed switch, Hall effect sensor (optional) |
The B5040 is particularly well-suited for applications involving hydraulic oils, diesel fuel, kerosene, water, glycol, and light chemicals. Its positive displacement design ensures that the measurement is unaffected by changes in fluid density, viscosity, or temperature (within the specified range), providing a true volumetric reading. This makes it a reliable choice for custody transfer, batching, and process monitoring where accuracy is paramount.
Installation is straightforward: the meter can be mounted in any orientation, though horizontal with the sensor facing upward is recommended for optimal performance. The pulse output can be directly connected to a flow computer, PLC, or a simple counter to display total flow or flow rate. For advanced monitoring, Rossonix offers optional display units and remote data logging solutions.

Frequently Asked Questions (FAQ)
-
Q1: What type of fluids can the B5040 measure?
A: The B5040 is designed for clean, low to medium viscosity liquids (1–1000 mPa·s). Common fluids include water, diesel, gasoline, kerosene, hydraulic oils, mineral oils, and many chemicals. It is not suitable for gases or highly viscous fluids like heavy crude. -
Q2: Do I need to install a filter upstream of the meter?
A: Yes, it is strongly recommended to install a 60-mesh (or finer) filter upstream to prevent particles from damaging the vanes or affecting accuracy. The meter is wear-sensitive to solid contaminants. -
Q3: What is the minimum flow rate for accurate measurement?
A: The meter can measure down to approximately 10% of its full-scale range with acceptable accuracy. For the smallest model (0.5–5 L/min), the minimum reliable flow is about 0.5 L/min. Below that, accuracy may degrade. -
Q4: How do I calibrate the B5040 flow meter?
A: The meter is factory-calibrated and typically does not require recalibration under normal use. If recalibration is needed, it should be performed by a qualified technician using a gravimetric or master meter method. Rossonix offers recalibration services upon request. -
Q5: Can the meter be used with a pump that has a pulsating flow?
A: Positive displacement meters handle pulsating flow better than many other types, but severe pulsation may cause fluctuation in the reading. Installing a pulse dampener or accumulator upstream is recommended for smooth operation. -
Q6: What is the expected service life of the B5040?
A: With proper installation and maintenance (e.g., clean fluid, regular filter replacement), the meter can last many years. The rotary vane mechanism is durable, but vanes may wear over time depending on the fluid and operating conditions. Spare vane kits are available. -
Q7: How do I connect the pulse output to a PLC?
A: The standard pulse output is an open-collector NPN (or optional PNP) signal. You can connect it to a digital input module of your PLC. A pull-up resistor (typically 1–10 kΩ) may be needed if using NPN output. Refer to the wiring diagram provided with the meter. -
Q8: Do you have a model with a digital display?
A: The B5040 is a flow meter without an integrated display, but we offer compatible battery-powered or loop-powered flow rate/totalizer displays that can be mounted separately. Please inquire for details.
