Product catalog summary

Introduction
Bronkhorst® has developed the MASS-VIEW® series, an innovative range of mass flow meters, regulators, and controllers with integrated displays. These devices offer a modern and economical alternative to traditional variable area meters (VA meters) by measuring mass flow instead of volume flow. The mechanical design allows for easy replacement of VA meters with common process connection options.

MASS-VIEW® Series Features
The MASS-VIEW® series operates on direct thermal mass flow measurement, eliminating the need for temperature and pressure corrections. Key advantages include higher accuracy, a wide rangeability of up to 1:100, and a safer construction without glass components. The devices feature a bright OLED display for easy reading of flow rates, total flow, and gas type. Additional functionalities include alarm and counter functions, analog and digital outputs, and optional flow control via a needle valve. An integrated auto-compensating controller ensures steady flow despite upstream pressure variations.

Technical Specifications

Accuracy: ±2% RD for flows over 50% of max capacity.
Repeatability: <0.2% FS typical.
Pre-installed gases include Air, Ar, N2, O2, CO2, CH4, C3H8, N2O, CO, and C4H10.
Operating pressure: 0–10 bar(g) / 0–150 psi(g).
Operating temperature: 0–50 °C (32–122 °F).
Materials: Aluminum, Viton®, SS316, PTFE, and others depending on the model.
Electrical connection: 8-pin RJ-45 modular jack.
Output: Analog (0–5 Vdc) and digital (RS232/RS485).

Applications
The MASS-VIEW® series is suitable for various applications, including burner control, welding gas monitoring, leak measurements, coating, gas consumption measurement in hospitals, and more. It is also used in laboratories for flow rate monitoring and in the food and pharmaceutical industries for processes like fermentation and blanketing.

Software Tools
Bronkhorst provides free software tools such as FlowDDE, FlowPlot, and FlowView for interfacing and optimizing digital instruments. These tools are available for download from the company's website.

Ordering and Availability
The MASS-VIEW® products can be ordered online from Mass Flow ONLINE B.V., with competitive pricing and fast delivery within two working days.

MASS-VIEW® The intelligent alternative for VA meters: mass flow meters for gases with flow display

Open the catalog to page 1

Bronkhorst®, specialists in low flow measurement and control, have designed an innovative series of mass flow meters, regulators and controllers with integrated display. The MASS-VIEW® series provides modern, novel and economical alternative to variable area meters (VA meters), also known as purge meters. Unlike conventional VA meters these new flow meters measure mass flow instead of volume flow. For easy VA meter replacement the MASS-VIEW®'s mechanical construction offers the most common options for process connection on the market. Bronkhorst designed MASS-VIEW® series operate on the principle...
