Weather station gas barometer - is adjustable for altitude using regulator piston in measurement fluid container

摘要

The regulatable gas barometer esp. for weather stations consists of a thermometer and of a barometer showing the temp. and air pressure. Two parallel vertical indicator tubes contg. fluid show the ambient air press. and temp. It is an easily regulated device with easily operated parts enabling adjustment for each air pressure esp. for variations with altitude. The loss of gas for the pressure display due to incorrect handling (i.e. orientation) of the device is prevented. The indication height (4.1) can be adjusted to the ambient air pressure using a slidable regulation piston (6) in the measurement container (1). A spongy porous stopper (8) is placed at the junction of the measurement container (1) and indicator tube (4). The functional pressure measurement components are contained within the housing (5.1).
