We Can Make Sensors to Measure Anything!
SMD Fluid Controls is a manufacturer and supplier of a wide variety of fluid sensors, float switches, temperature gauges, and liquid level sensors, including standard off-the-shelf products and custom sensors designed to meet your specific needs.
We work to lower costs and increase productivity for all of our clients, offering competitive pricing for OEM designs and applications. These include liquid sensors, machined level sensors, optical switches, ultrasonic level measurement, and custom molded float switches in metals or plastics like stainless steel, polypropylene, and nitrile butadiene rubber (NBR). Contact us today to get started.
Continuous Level Sensors
The FM-Series float switches are ideal for continuous liquid level detection applications. These versatile devices can be manufactured to custom specifications that include internal or external mounting, different lengths, and three distinct output types. The standard FM-Series float switches have a stainless-steel stem, which provides corrosion resistance and versatility across a variety of liquid media.
Vertical Float Switches
We provide full size, miniature, specialty, and customized vertical float switches in stainless steel and plastic float switches for a range of applications. Mounted to the top or bottom of a vessel, these versatile pieces produce an electrical signal when liquid reaches a specified level.
Horizontal Float Switches
Side Mounted Liquid Level Sensors are ideal for tanks or vessels without accessible mounting points at the top or bottom, such as aquariums or open vats. These pivoted or angled level sensors are available in stainless steel or plastic.
Custom Multi and Dual Liquid Level Switches
Designing your own fluid level sensor or pump control is easy with SMD Fluid Controls. Our engineers will work with you to design custom, a multi level switch for measuring and regulating fluid levels in any tank or vessel.
Optical Liquid Level Sensors
Capable of point level sensing and pressure level sensing up to 2500 psi, optical liquid level sensors work with no moving parts and built-in electronics. Well-suited for tanks or vessels of almost any size.
Ultrasonic Liquid Level Sensors
Ultrasonic liquid level sensors are incredibly accurate, cost-effective, and ideal for atypical or difficult fluids like acids or wastewater, ultrasonic liquid level sensors are essential for many industries and applications.
Liquid Level & Temperature Sensors
Streamline your fluid system by using one of our combination level/temperature switches, which act as level monitors and temperature sensors in a single unit. Minimize costs and simplify assembly.
Custom Temperature Sensors
Reliable temperature measurements are crucial in many industrial liquid processes – be confident with SMD’s custom temperature switches, which are ideally suited to a diverse array of control and monitoring.
In-line, piston style switch that monitors the flow of a liquid. Can be paired with other flow sensors or float switches for a number of fluid monitoring applications.
Mechanical Sump Switches
Mechanical sump pump float switches provide direct control for sumps and open tanks. “Pump Down” and “Pump Up” models are available, with custom options to meet a variety of needs.
Downhole Submersible Level Sensors
Submersible level sensors are versatile components that gauge tank levels by measuring hydrostatic pressure, providing stable, continuous output in depths of up to 211 meters.
Accessories and Electronics
Electronics and Accessories are used in tandem with SMD Fluid Control liquid sensors help to get accurate and repeatable fluid measurement readings in a vast number of applications.
