It can be difficult to tell if an installed flowmeter is on the certified list. Casting codes on the meter body may differ from the model number, or a meter label can wear off or be removed. Also, manufacturing companies merge, so your meter may appear on the list under a different name. We will help you investigate whether your meter is listed, but we will need to know the meter manufacturer, serial number or casting number, nominal pipe size and meter dimensions. A photograph of the flowmeter can be very helpful when trying to identify a flowmeter.
