AbstractAlow‐cost rapid response system to remotely collect piezometric head data in compressible porous media has been constructed. The system is based on low‐cost temperature compensated pressure transducers, standard low‐cost CMOS logic devices, low‐cost commercially available two‐way radios and a portable microcomputer. The basic system operation involves encoding a pressure transducer output, which is then transmitted on command via two‐way FM radios to a base station located up to one‐half mile away. The base station includes a TRS‐80 Model 100 microcomputer which controls the network of remote stations and decodes and stores the information. This information is partially processed in the microcomputer and may be readily transferred to a mainframe for further data analysis. The base station interrogates as many as 16 remote stations at a specified sampling rate. The versatility of the system also allows it to be used to operate any remote instrumentation system having a suitable
