Suction Lance with Continuous Level Measurement for Chemical Reach Prediction

28.04.2021
Chemicals always run out when you least expect it. This is now a thing of the past with the new continuous suction lances from ProMinent. Not only does the lance ensure that liquids are reliably withdrawn, it also monitors the current level at the same time.

Connected to diaphragm metering pumps like the GMXa and GXLa, or the peristaltic metering pump DFXa, the level (in containers up to 30 liters) is measured and shown on the pump display; specified in percent or in liters. Due to this, the chemicals can be refilled in time. The full potential can be maximized when the pump and the continuous suction lance are connected to a PLC or even DULCOnneX. With DULCOnneX the consumption is recorded and displayed graphically which enables the user to always have an eye on the containers, and can refill them in time.

All conductive liquids with a dielectric constant of over 30 are monitored. These values are recorded by almost all water-based acids or alkalis. The commonly used chemical, sodium hypochlorite, can also be measured without any problems. Based on the measuring distance of 460 mm, the level measurement accuracy is 2.5 percent. Individually adjustable warning and error levels can be set. It can, for example, be set that a warning is displayed at a level of 20 percent and an error message at a level of 5 percent.

Location-independent system monitoring in real time
A connection to the DULCOnneX Platform offers further options. Networked with the digital fluid management solution, the pump installation including the suction lance can be monitored and recorded in real time. Decisive advantage: The remaining range is also displayed - e.g. whether the content will remain for two or three days. The exact duration is calculated from the dosing quantity of the pump and the level. This reliably prevents production or process downtimes due to a lack of chemicals. This means that the containers can always be replaced or refilled in time.
