Remote mountable flowmeter for small line processes
As process and plant engineers focus continuously on improving plant efficiency and capacity, they frequently must add more points of measurement to achieve these improvements, which requires additional space for the required instrumentation.
Whether adding flow sensing to improve a process or replacing poorly performing or high-maintenance flow meters, the ST75 Series Flow Meters offer a remote mountable instrument that provides an accurate, fast response and low-maintenance solution to small line size gas and air flow applications.
It is suitable for a wide range of industrial applications, including burner and boiler fuel and air feed lines, industrial furnaces, kilns and oven fuel/air controls, natural gas sub-metering, chiller air flow measurements, dosing and gas injection rate controls, air compressor system control and point-of-use monitoring, and co-gen and turbine generator fuel flow measurements.
It is the perfect fit when space is tight in small line processes requiring high performance combined with reliability and safety requirements.
The ST75 Series Flow Meters are a compact, low cost solution for the direct mass flow measurement of air and gases.
These in-line (spool-piece) style flow meters have no moving parts and are available for use in pipe diameters from 0.25 to 2 inches, (6 to 51 mm). Process connection options include male NPT, female NPT, and flanged. These thermal flow meters feature wide 100:1 turndown and depending on pipe size, will measure from 0.01 to 559 SCFM (0,01 to 950 NCMH).
The ST75 Series’ electronics are housed in a rugged, IP67 rated enclosure with dual conduit ports in either NPT or M20 threading. The instrument comes standard with dual 4-20 mA outputs and a 500 Hz pulse output. The Models ST75A and ST75AV include HART or Modbus, as well as NAMUR compliant 4-20 mA outputs and SIL compliance rating.
This flow meter's transmitter/electronics can be integrally mounted with the flow element (probe), or it can be remote mounted to best match the installation situation.
The remote mount transmitter, which includes a full digital display, can be mounted up to 50 feet (15 meters) away from its thermal mass flow sensor in the process piping and connected via two 0.50-inch FNPT or M conduit connections.
