Designed especially for small flow volumes - Deliver fluids with high precision and an accuracy of ± 0.5 per cent
Darmstadt, October 2013 – Whether you are dealing with oil, acids or water – Schenck Process presents a newly developed loss-in-weight feeder especially designed to handle small flow volumes: the MechaTron® LQ S. Contrary to its “big brother”, the MechaTron® LQ M, the MechaTron® LQ S uses platform scales with only a single load cell. As a result, small flow volumes in the range of 0.25 to 150 kg/h can be realised. In addition, the MechaTron® LQ S, which is made completely of stainless steel, has a feeding accuracy exceeding ± 0.5 per cent and a wide range of applications. That allows liquids with temperatures between 5 and 100ºC and viscosities between 0 and 1,000 mPas to be fed in. Furthermore, the feeding system can be implemented in ambient temperatures of -10 to +50ºC.
The MechaTron® LQ S is available either as a gravimetric feeder or as a volumetric Loss-in-Weight Feeder with or without a weighing module and decoupling. Should the customer choose the gravimetric system, the MechaTron® LQ S uses a regulated pump. With this configuration, the actual feed rate is determined from the decrease in weight per unit time. The control system compares the actual feed rate with the pre-set target feed rate and regulates the pump’s feeding performance. In order to achieve highly accurate weighing results, the pump is separated from the weighed section. That offers the considerable advantage that the MechaTron® LQ S can be used at a counter-pressure of up to 70 bars without adversely affecting the measurement’s accuracy.
The measurement, control and regulating electronics of the mechatronic version can be directly integrated into the mechanics, or placed in a control cabinet or wall housing according to individual customer requirements.

The MechaTron® LQ S can also be delivered with a hopper and lid made of stainless steel material no. 1.4404/1.4571, an agitator for the feed hopper, a mobile collection tray and a special lid for manual filling. Additional extras include electric heating and/or insulation, and silicone-free seals and decoupling elements.
Schenck Process will be presenting this new product at the K 2013 exhibition from 16 to 23 October. We look forward to seeing you at booth E 77 in hall 11.
