Large, clear scale for quick and accurate measurement reading
VERSATILE + ROBUST
To enable cleaning and replacement of the metering assembly, the Model EHR has a quick change tube and is only available with the valve on the outlet. This model is one of the EH Series flow meters which are one size up from the versatile EM range of meters. Other Model EH configurations with or without a flow control valve include the Model EHI and EHO with a flow control valve on inlet or outlet respectively. The base Model EH has no flow control valve, enabling flow vertically through the meter. The slotted side plate design on Model EH meters allows for easy flow level alarm installation. Configured for seal water monitoring applications, a pressure gauge can be attached to model EHI.
