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

The FMA-1600A and FVL-1600A Series mass and volumetric flowmeters use the principle of differential pressure within a laminar flow field to deterime the mass flow rate. A laminar flow element (LFD) inside the meter forces the gas into laminar (streamlined) flow. Inside this region, the Poiseuille equation dictates that the volumetric flow rate be linearly related to the pressure drop along a fixed distance of the LFE. This, along with the viscosity of the gas, is used to accurately determine the volumetric flow rate. Separate absolute temperature and pressure sensors are incorporated and correct the volumetric flow rate to a set of standard conditions. This standardised flow rate is commonly called the mass flow rate and is reported in units such as standard cubic feet per minute (SCFM) or standard litres per minute (SLM).
Standard units include a 0 to 5 V output (4 to 20 mA optional) and RS232 communications. The gas select feature can be adjusted from the front of the keypad or via RS232 communications. Volumetric flow, mass flow, or absolute pressure, and teperature can be viewed or recorded through the RS232 connection. It s also possible to multi-drop up to 26 units on the same serial connection to a distance of 38 metres. These flowmeters can be powered by the optional battery pack FMA1600-BP for use in the field.
The FVL-1600A Series comprises volumetric flowmeters only. They do not measure or correct for absolute pressure or temperature. The FMA-1600A Series is recommended if the operating pressure is above 10 psig or if there is any restriction or backpressure in the applications.
