Keystone Compound Water Meter

Description:

This is a compound water meter that fit a 2” pipe. The Pittsburgh Meter Company introduced the Keystone meter in 1901, and the Pittsburgh Equitable Meter Company was still producing it in the late 1930s. The serial number (1,648,433) suggests that this example was made in the late 1920s. Pittsburgh Equitable explained that this model “consists of a combination of two units for measuring both the large and small flows of water, together with an automatic valve mechanism for controlling both flows so that the small flows will automatically pass through one unit and the large flows through the other unit at exactly the proper time and with as slight absorption or loss of pressure as possible.”
