The application of new pattern frequency conversion and constant pressure to water supply equipment

At present,the water supply equipment of frequency conversion and constant pressure,always used with the programmable logic controller of the analog input / analog output or PID regulator,the PID algorithm programming and programmable logic controller programming are very difficult ,equipment costs are high and it's difficult to debug.In order to resolve these questions,the water supply equipment of constant pressure was produced,which is using the built-in PID function and built-in pump logic control funct...
