Flow Indicator
Loading and off-loading fuel from a transport truck is easier than ever with the bottom loading adapter. While loading, a free float poppet design keeps the handle in the closed position as long as the poppet is activated. During off-loading, the handle's two open positions adjust the flow rate.

The lightweight, heavy-duty adapter is engineered and tested to meet API RP 1004 specifications. The outer end is hard-coated aluminum and rotates to prevent uneven wear sometimes caused by terminal and off-loading couplings. Compatible with all API dry disconnect couplers.

The adapter is constructed with a standard TTMA 4-inch tank truck flange and mounting lugs for EBW Air Interlock Valve. Dimensions for Canadian versions are the same as the line drawings shown.

The EBW Flow Indicator gives a visual indication of product in the line.
