Smartflow® hot oil/water flowmeters are durable, vane-operated devices that provide visual indication of flow rate. The indicator ball is separated from the process by a high temperature gasket and stainless steel plate. A glass window retains the indicator ball. This flowmeter is designed specifically for hot oil or hot water circulating loops in industrial processes.
