Switzer flow switches / indicators are versatile instruments designed suitable for different pipe sizes with sensors such as Paddle, Piston, Valve disc to handle any fluid. Delta tube, multi port averaging Pitot Tube flow element, is an excellent device which provides stable differential pressure output. Delta Tube has low installation and operating costs which is a major factor in large diameter piping and results in energy savings and years of trouble-free operation
