Peterbilt Batching Application Industry: Motor Vehicles and Equipment

SIC Code: 37-1

Application:
Batching of solvent that is used to clean chassis before painting. In the case of Peterbilt, the EPA allows no more than 32 ounces to be sprayed on each chassis. The Hoffer batch controller has reduced the amount of solvent used and provided a verification method for the EPA.

System Requirements:
Must be highly accurate at a low flow rate.
Must only allow set amount per spray.
Must totalize monthly usage.

Solution:
Hoffer Mini-Flowmeter: MF½X100A-.06-1.6-B-1MC3PAX-MS Flowstar 2007A-X-R2-1-1-RF-X-DSR-1-HO/LO-NI-X The Hoffer Mini-Flowmeter and Flowstar Batch Controller were installed just outside the paint booth. The manufacturer set Flowstar 2007 to close a valve after 31.5 ounces of solvent have been dispensed via a spray gun. The operator must then press a reset button in the paint booth before the next chassis enters to initialize the Flowstar for another 31.5-ounce batch.

Hoffer Advantage:
Meter calibration is NIST traceable.
Higher accuracy at a low flow rate than paddlewheel meter.
The use of Flowstar improves flowmeter linearity via linearization.

Summary:
The system allows Peterbilt to stay within the EPA’s limitations on VOCs in their production environment and control an expensive product’s usage. It also ensures that the information supplied to the EPA on monthly usage is accurate and verifiable.
