Water Meters

Mid 19th century to early 20th century

During the second half of the 19th century, the Portuguese engineer, Antonio Pinto Bastos registered the patent to this low-pressure tilting water meter.  It consists of a parallel piped box, with 2 equal oscillating containers that would alternately fill with water. A clockwork system registers the number of times that these containers would release water. A small number of this model were produced in a larger size and without automatic valve.

In mid-20th century, they became obsolete, the company having decided to replace them with positive water meters.

These low-pressure water meters were also known as “Bastos’ water meters”, “stroking water meters” or “tilting water meters”.

This item has the producer’s number 8254.
