HIGH-TECH replacement for VA METERS
The MASS-VIEW® flow meter series are a digital alternative to the conventional variable area meters. The MASS-VIEW® flow meter series incorporates a digital bar graph of actual gas flow as well as indicating flow units, gas type and totalised figures.
The MASS-VIEW® series operates on the principle of direct thermal mass flow measurement. It offers a standard accuracy rating of ± 2%RD if the flow is higher than 50% of it’s maximum full scale and ±(1%RD + 0.5%FS) on lower flows, flow ratings from 0.2 up to 200 ln/min, and handles pressures up to 10 barg. The MASS-VIEW® incorporates the latest OLED technology, which gives a brighter readout than LCDs, can be viewed from virtually any angle and has fast signal response times. Alarm settings and the selection of a gas/range are accessed via menu. An analog output signal enables data logging against various parameters and full accountability of gas flow.

SCHMIDT® Flow-sensor SS 20.260 for process technology
For the employment in process technology the latest SCHMIDT® flow sensor SS 20.260 offers three crucial upgrades compared to his forerunner. With an expanded measuring range of 0 … 50 m/s the sensor can be applied for flow rate control in a wide range of systems. Many processes require the measurement of heated gases and therefore an enhanced operating temperature. Depending on the configuration of the SS 20.260 it is up to 120 °C. The temperature can be measured with an additional linear output and no separate sensor is required any more. The unit is ro-bust due to a chamber in which the sensing element is protected against impacts. The stainless steel sensor tube is available in different length and thus can be placed at the correct position regardless of the size of the duct. Two LED’s indicate the correct operation or inform about wrong supply voltage or sensor defects.
Applications: Flow measuring in air ducts, volume flow measur-ing in test benches, control of combustion air of oil, wood, gas or coal burners, flow control in cool-ing or drying constructions.
Technical data: Immersion sensor with integrated transducer.
Use of sensor: Free air and guided air in ducts from 25 to 1.000 mm (1 to 40 inch).
Medium: Air, Nitro-gen, Argon and other non-burnable gases. Measuring ranges: 0 … 2.5/10/20/40/50 m/s.
Pressure: Atmospheric.
Power supply: 24 VDC / power consumption only 30 mA.
Output: 0 … 10 V / (0)4 … 20 mA linear.
Functional display: 2 Status LED’s
