Flow Sensors

Flow Sensors are essential components for controlling the flow rate of liquids, gases, steam, and other fluids. They are typically designed to measure flowrates within limits specified by the manufacturer, then alert the operator when the flowrate exceeds those limits. Flow Sensors come in a wide variety of types, each with its own unique application field and working principle.

The LFS-04/H Flow Sensor is a type of pressure transducer commonly used in fluid flow control systems. It utilizes a differential sensing concept to measure and display flow rate in two modes - direct or digital output. In direct output mode, the flow is indicated on a pressure transducer-style display with a mA or VDC output, whereas in digital output mode, the flow rate is indicated on a digital display. The direct output mode can be used for simple flow control applications while the digital output mode is suitable for flow control systems requiring data transfers between devices.

In direct output mode, the LFS-04/H works by measuring the difference in pressure between two points in the flow line. The pressure sensor is mounted between these two points, allowing for continuous measurement and output of the flow rate. The output signal is calibrated for different flow conditions and is used to control the flow rate. The flow rate ranges from 0.1 ml/min to 10 liters/min.

When using the digital output mode, the pressure sensor measurements are read by the digital display. The system uses a non-intrusive approach to read pressure changes and transmit the data to other devices for further processing. The user-programmable output can be used to monitor and control the flow rate, or to display the readings in various formats. This mode can measure up to 10 liters/min of liquid or gas, with an accuracy of up to 0.01%. It can also be used for batch control, meaning the user can set a predetermined volume for a batch and monitor the progress.

The LFS-04/H Flow Sensor is ideal for a variety of process control applications, including medical instruments, gas and liquid metering, food processing, environmental control, chemical processing, and aerospace systems. It is a reliable and economical device, designed for ease of use and scaleability. With its impressive performance, low maintenance requirements, and great value in relation to cost, it is one of the top choices of scientists, technicians, and engineers.
