The Dwyer Instruments VA1045 Variable Area Glass Flowmeter is a glass-tube flowmeter that uses the variable-area principle to indicate flow rate. Model VA1045 is part of Dwyer’s flowmeter lineup and features a transparent glass body that provides direct visual confirmation of flow conditions along the measurement path. As a mechanical, non-electronic device, it relies on a float moving within a tapered tube to show the current flow and offers inline flow indication without power requirements. The glass construction enables clear visibility of the flow through the tube, helping operators quickly assess system performance at a glance.
