This Chart No. 37 Serial No. D1861 meter could measure Temperature 0 - 100'F and Relative Humidity 0-100% r.h. c/w 2 ink bottles, 2 ink applicator stoppers. The Thermograph chart is printed in red ink on off white paper.

Close-up

Hollowed out logs of variable lengths were used to transport manufactured gas. They were milled to have a male end and were wound with spirals of loosely spaced iron bands as well as coated on the outside with asphalt or similar bituminous substance.

Cast iron, low pressure leather diaphragm 550 ft3/hr. Meter repaired at Union Gas from 1930's until 1970's. By today's standards, it would have been used in a small commercial application.

Cast iron, high pressure leather diaphragm 400 ft3/hr. Meter repaired at Union Gas from 1930's to 1970's. Used when heaters required on high pressure stations.

Cast Iron, EQU/W Volume/pressure recorder. Very limited use at Union Gas.

The water pressure temperature recorder was adaptable to different manufacturers' meters through mechanical linkage. Used by Union Gas during 1950's, 60's and 70's.

The Tobey Meter was developed in 1891. Cast Iron Meter with 3 leather diaphragms and available in 4 sizes. This is an example of second smallest.

First developed in 1889 by Metric Metal Co. in Pennsylvania. It has 2 leather diaphragms (standard meter configuration) and was used and repaired at Union Gas until Mid 1970.

Tobey was a small residential meter used and repaired by Union Gas.

Limited use at Union Gas.

American Tin Case Meter was first developed in 1905. 5B (or 5 light) residential meter popular with Union Gas and used through the 1960's. (Note: wax Government Inspection Seal)

Used to test for leaks on new pipe installations in 1930's. Used in field by an inspector.

They are used to measure the pressure exerted by a gas and generate a test pressure for the calibration of pressure gauges, electronic pressure calibrators, transducers, transmitters, records, etc.

No other device can match the stability, repeatability and accuracy of the deadweight tester. Accuracy - 0.05% of indicated pressure, traceable to the National Institute of Standard and Technology (NIST). Weight, 80 pounds. Used in field testing.

Temperature Compensated Tangent from a large diaphragm Rockwell Meter approx. 1975 - 2000. From an RC10000 which was the largest diaphragm meter made by Rockwell used in commercial applications, eg. Churches, Schools, etc.

Repaired at Union Gas beginning in 1970's and are now replaced with electronic modules.

First "dry meter" used in mid 1800's with viewing windows to enable customers to see how they worked. This was an indoor meter usually installed in the homes of affluent people to "show off" having natural gas service and are often highly decorative.

It widely used by Union Gas from 1950 as a residential meter. Model number has changed to ACM250 and is still used today. It consists of an aluminum case, rubber diaphragm and temperature compensation was added in 1975.

American Meter WI-45, 45 cu. Ft./hr. 1960 demo meter. Not used at Union Gas. An example of a very small meter for use in a residential setting.

It has an aluminum case and was used by Union Gas in small quantities for residential meters until 1960's.

It has an aluminum case and was not used by Union Gas for residential meters.

This was not used by Union Gas.

The superior steel cased meter was an older version and probably not used by Union Gas. Newer versions with aluminum cases were used at Union Gas.

Stainless Steel used to measure large volumes of gas in pipelines, where there was constant flow pressure.
