Sino-Inst has designed and manufactured flow switches, level switches and controllers for many years. A switch is a simpler decision than a transmitter, but it goes wrong in the same places. Before choosing one, pin down: the medium, the flow rate or level at which it must trip, pipe or tank size, contact type (normally open or normally closed) and electrical rating, process temperature and pressure, wetted material, and how it mounts.
These guides cover the main switch and controller types: how each works, where it suits the job, and where its limits are. They run across paddle and thermal flow switches, float, tuning fork, capacitance, RF admittance and ultrasonic level switches, plus level controllers and mass flow controllers. Read alongside our product specifications, they should get you to the right device.
Or simply tell our sales engineers what you need to measure, and we will put a measurement solution together for you.
