More Powerful Pressure Transmitter with Diaphragm Seal and Capillary

by

Diaphragm seal is used to prevent media from directly entering the sensor assembly in the pressure transmitter/differential pressure transmitter. Remote split pressure measurement can be achieved by connecting the fluid-filled capillary tube to the transmitter. Diaphragm seals effectively broaden the application range of pressure transmitters. It makes the measurement of pressure transmitter and differential pressure … Read more

What Is the Flow Rate? Velocity vs Flow

by

What Is the Flow Rate? Is the flow rate the same as Flow? When we choose a flowmeter, we often know the fluid parameters of the pipeline. Including flow range, pressure, pipe diameter, etc. Flow rates and flow ranges are different. Flow is divided into volume flow and mass flow. So what is the relationship … Read more

Level Measurement: Why & When Is a Stilling Well Needed?

by

Stilling Wells are ingeniously designed to suppress liquid surface fluctuations and turbulence, ensuring high-precision level measurements. Surface disturbances are a problem in level measurement, whether using contact or non-contact methods. By isolating a calmer liquid column, Stilling Wells provide the sensor with a clear and stable target, eliminating misreads. Sino-Inst has assisted customers in applying … Read more

Liquid Concentration Meter – Optical Principle

by

Optical liquid concentration meters calculate concentration values ​​based on the different refractive indices of media with varying concentrations. They utilize the diffusion characteristics of light spectra in liquids, sampling through a high-resolution spectral sensor, and analyzing the data using software to determine the concentration patterns. Temperature compensation is then applied to measure the concentration of … Read more

Sea Water Resistant Pressure Sensors

by

Pressure sensors are widely used in various fields such as ship systems, desalination plants, subsea equipment, and environmental monitoring.
