Flow Monitoring System for Conformal Coating from Nordson ASYMTEK

Flow Monitoring System

Nordson ASYMTEK's Flow Monitoring System aids in closing the dispensing loop for conformal coating. Flow monitoring confirms that products have been coated with the correct amount of material with a resolution of ± 0.04 ml.

The Flow Monitoring System measures the volume of material dispensed on a product against an established target. The Nordson ASYMTEK Easy Coat® software logs all data (amount of material dispensed) to a log file and database. The data is displayed on the computer screen in bar graph format with time history.

High and low limits for dispensed volume are established during product programming. In operation, the PC system controller together with Easy Coat software, monitors the gear-type flow meter when the coating sequence begins. The Easy Coat software records and displays the data on the graph. If the dispensed volume is outside the present range, the system can be programmed to stop and sound an alarm, pause or continue dipensing.

The Flow Monitoring system consists of three major elements: the gear-type meter that fits in the fluid line, an interface board, and Easy Coat software.

The Flow Monitoring System is designed for use with Nordson ASYMTEK's S-940E/S-941-E conformal coating systems that are equipped with the SC-204/205, SC-280N, SC-300 or SC-400 applicators.

Features

  • Flow monitoring occurs during production without affecting the cycle rate or increasing material usage
  • Flow monitoring confirms that the correct amount of material is dispensed with a resolution of ±0.04 ml
  • The operator is alerted when an adjustment is required to prevent possible defective products 
  • Stainless steel construction ensures the Flow Monitoring system is compatible with all conformal coating materials
