Flow ComputersOCi-1000M SeriesThe 1000M has been used as general purpose hardware platform for a variety of stand-alone or networked instruments mostly related to flow measurement. It has either 4 or 8 analog inputs and one or three analog outputs (typical 4-20 mA signals) and a 24vdc Power Supply to energize all input and output loops.

Some
of the application software running on this platform are: Chilled/Hot Water BTU Computer Most
widely used application, it collects data in real time from any type of flow meter
and two RTD sensors. Data is displayed locally on counters as Total Btu’s,
Ton-Hrs, Gallons, and instantaneous flow rates in Btu/hr, Tons, GPM etc. Steam Flow Computer Most common application is saturated steam metering from flow rate and saturation pressure. Totalizes pounds or Kg of steam and displays instantaneous flow rate. Superheated steam requires a steam temperature input as well. In orifice metering of steam, dual DP’s across a common orifice may be used to extend turn-down. The computer auto-selects the DP Transmitter. Gas Flow Computer Natural gas or any other fuel may be metered from flow meter, pressure, temperature inputs. Computes SCFM and totalizes SCF or mass. All above may be networked in a serial RS-485 loop and polled by the OCI Energy Management PC program (EMS) running under Win95/NT. Real time monitoring and retrieval of stored data in each field unit are common tasks of the EMS. Information is used by District Energy companies for billing and/or maintenance purposes. |
