SIC Code: 33X12

Application: To monitor oil spray on the top and bottom of a continuous feed steel sheet for quality assurance and optimization of oil coating. In addition, to monitor return flow of unused oil to a storage tank to provide total oil used. Steel manufacturers use oil at various stages in the process of making steel. Some examples of specific uses follow: Oil, in combination with water, may be used as a cooling agent to quench steel which has been subjected to intense heat. It may be applied to the surface of steel for rust protection or to prevent scoring in case the steel rubs together.

System Requirements: An oil supply monitoring system used in the sheet steel industry should be accurate, repeatable, but above all it must be reliable. Lack of oil on the steel sheets during processing may result in the failure of the processing machinery causing expensive down time or poor quality steel.

The flow monitoring system must measure the total spray via multiple lines and the excess oil collected in the sump and returned to storage. A multi-input flow computer is also needed to provide instantaneous rate and total for each line.

Solution: A 3/8" HO Series Turbine Flowmeter for Gas to meter air. Flowmeter Model# HO 1/2 x 3/8-15-B-1MC2PAX-MS Operating Temp: +70 F. Operating Pressure Range: 40 to 50 PSIG. Flow Range: .5 to 5 ACFM. Model ACC32-1-C-D-X-4/0 Flowmeter signal conditioner/converter with 4-20 ma analog option. This conditioner with the modulated carrier pickup coil improves turbine flowmeter rangeability. The enclosure type is style 4 which is integrally mounted on the meter and suitable for hose down. Hoffer Advantage: The Hoffer flow system offers an economical and accurate solution for air measurement. It is easily incorporated into the customer's operation. The 3/8" gas turbine flowmeter teamed with the ACC32 provides the user with a metering system that yields wide rangeability, long term accuracy, and flowmeter linearity of ±1% or better. The response time of the HO meter is approximately 7 to 10 milliseconds.. Summary: The flow system allows the customer to accurately measure air and is incorporated into their operation easily. This process is much like the use of a spray gun, with the flowmeter measuring the amount of air to control the amount of liquid necessary to coat the pills. The ACC32 signal conditioner/converter sends a signal representative of flow rate back to the customer's data acquisition center for process control.
