APT221 Water Supply Ceramic Pressure Transmitter
Water Supply Pressure Transmitter
Introduction
In the water supply and water treatment industry, variable frequency constant pressure water supply system is a trend of development, which has the advantages of high efficiency, energy saving, stable pressure, reliable simple operation, convenient installation, less occupation, low noise, no pollution, less investment and higher benefit.
APT221 series pressure transmitter is specially developed for the special needs of variable frequency constant pressure water supply system. With buffer screw which designed for water hammer, it plays a role of pressure sensing, signal receiving and feedback in the variable frequency constant pressure water supply system.
