Abstract

A simple device was developed for measuring pressure in thin—walled collapsible emitting hose or tubing in the
field. The device, called a "Squeezer," senses pressure by measuring the force necessary to compress a short section of tubing
between two parallel plates to 50% of its original diameter. The force can be measured by either an electronic load cell or
a spring balance, and the output, calibrated for a particular size of tubing, read directly in pressure units. The device provides
a convenient, non—intrusive and low—cost means for irrigators to assess pressure variations within their microirrigation
laterals without installing special fittings or puncturing the tubing.
