Pump control - Import export

The ASCO LH900 Liquid CO2 Filling Pump has been developed as an universal unit for filling high pressure CO2 cylinders by weight. Like all ASCO Equipment, the Cylinder Filling and Weighing System is thoroughly factory pretested before despatch. Thanks to the separate control unit, the pump can be placed in a different location. Easy operation Switch on your ASCO LH900 and the unit automatically tares itself to „0“ which will show on the indicator display. After placing a cylinder on the platform, the display will show the accurate tare weight of the cylinder, allowing the operator to check whether the empty cylinder weight is correct. The chosen filling weight can now be set on the display by pressing the relevant keys (when filling the same size of cylinder, the filling weight needs only be entered once). When the desired filling weight is reached and displayed, the solenoid valves of the ASCO LH900 will automatically switch to run the system in bypass.

We offer various solutions for liquid dosing. Based on parameters such as flow rate, dosing accuracy, properties of the media process and regulatory requirements we select the appropriate method of dosing as well the most suitable dosing instruments. Dosing methods used, include gravimetric dosing with load cells, various types of dosing pumps and dosing with pumps using mass flow controller (MFC) and level sensors.

The process meter monitors and displays the analog measured values. Pumps can be monitored with the digital status inputs. The RIA452 can provide power directly to two-wire sensors connected. Up to eight freely programmable relays monitor the measured value. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions. Furthermore, the RIA452 can be used as a preset counter and for measuring flow at open channels and measuring weirs.
