Dispense Pump – Syringe Fluid Level

Available for all MAX Series and DS Series dispense platforms is pump syringe fluid level detection, and GPD’s programmable controllers

The optional Level Detect option uses a capacitive proximity sensor that generates an electrical field (Figures 1 & 2) to identify the level of material in a material syringe.

Figure 1: No electrical field connection or signal exists when syringe fluid blocks the sensor.
fluid level detection when syringe fluid level is low
Figure 2: Electrical field connection exists when syringe fluid level descends below the sensor.

Unlike an optical sensor, the Level Detect is not subject to syringe color or label limitations. The sensor position, rotation, and orientation are easy to adjust. The Level Detect is compatible with all GPD Global pumps and syringe sizes from 5 cc to 55 cc.

Shown on pump models: Precision Auger, NCM5000, PCD3H, and PCD4H

How the Dispense Pump – Syringe Fluid Level Works

The sensor lamp turns on (Figure 3), setting an “OK to Process” flag when the syringe is full or the fluid level is present above the Level Detect sensor. When the fluid level drops below the Level Detect sensor, the sensor lamp turns off (Figure 4), and a “Fluid Level is Low” system message (Figure 5) prompts the operator to add fluid.
