Causes and Solutions for Overloading in Batch Material Dispensing Control

PLC /

Overloading phenomenon is a common issue in the batch material dispensing control process. Specifically, when the total dispensing amount reaches the preset value, the controller immediately sends a signal to close the valve. However, due to system lag and inertia, some fluid continues to flow towards the receiving end, causing the final dispensing amount to […]

Integration of Flow Meters and Differential Pressure Transmitters

Pressure Transmitter /

The integration of flow meters and differential pressure (DP) transmitters is based on the principle of differential pressure measurement. The DP transmitter converts the small differential pressure signals generated by the flow element into standard electrical signals, enabling accurate flow measurement and remote transmission. This creates a symbiotic relationship between “flow measurement” and “signal conversion.”
