Float Switch
Float Switch

Float switches are versatile devices used for liquid-level monitoring in various applications. These switches rely on a floating element's buoyancy to control an electrical circuit's opening and closing. They find use in industries such as wastewater management, industrial automation, and residential sump pumps, where precise control of liquid levels is essential for safety and operational efficiency.

Radar
Radar

Liquid level radar products are devices that use radar technology to provide accurate and reliable measurements, even in challenging conditions such as high temperatures, pressures, and with corrosive or volatile liquids. Unlike traditional methods, radar level sensors are non-contact, meaning they do not touch the liquid, reducing the risk of contamination and wear. They are widely used in industries like oil and gas, water treatment, and chemical processing for their precision and durability. With real-time data and minimal maintenance requirements, liquid level radar products help optimize operations, improve safety, and ensure efficient inventory management.

Differential Pressure Control
Differential Pressure Control

Differential pressure liquid control products are essential components used in various applications to monitor and control the pressure difference between two points in a liquid system. These products are designed to measure the pressure drop across filters, pumps, valves, or other flow control devices. They are crucial in maintaining proper flow rates, preventing system damage, and ensuring optimal performance. Differential pressure liquid control products typically consist of a differential pressure transmitter or sensor, a flow element (such as an orifice plate, venturi tube, or flow nozzle), and associated piping and instrumentation. The transmitter or sensor detects the pressure difference and converts it into a proportional electrical signal, which can be used for monitoring, control, or alarm. These control products find applications in oil and gas, chemical processing, water and wastewater treatment, and HVAC systems. They help optimize system efficiency, improve process control, and ensure liquid systems' safe and reliable operation by providing accurate and real-time differential pressure measurements.

Float Switches
Float Switches

Float switches are essential components used in industrial manufacturing to detect and control the level of liquids within tanks, vessels, and pipelines. Designed to provide dependable point-level detection, these switches operate by responding to the rising or falling motion of a float triggered by liquid presence. When the float reaches a set point, it actuates a switch to signal high or low levels, start or stop pumps, trigger alarms, or control valves.
