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

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 Stilling Wells to various scenarios, from wastewater lifting stations to food processing tanks.

Sea Water Resistant Pressure Sensors

Pressure sensors are widely used in various fields such as ship systems, desalination plants, subsea equipment, and environmental monitoring. These fields are distributed in marine, offshore, and coastal areas. However, seawater is one of the most corrosive natural media because it contains a high concentration of sodium chloride, and chloride ions are highly corrosive. Therefore, traditional stainless steel materials perform poorly in marine environments. This article aims to introduce our pressure sensor, specifically designed for seawater corrosion resistance.

Industrial Smart Pressure Transmitters 4-20mA, HART, RS485 Modbus

Industrial smart pressure transmitters are microprocessor-based high-performance transmitters. With flexible pressure calibration function. Instrument equipment commonly used in industrial process control can convert fluid or gas pressure into standard analog signals (such as 4-20mA) or digital signals (HART, RS485) and output them to the control system. Beyond 4–20 mA, HART and RS485 Modbus, pressure can also be reported over a CAN network — see our CAN bus pressure transducer with CANopen and custom CAN 2.0B output.

What Is a Density Meter? And Guide to Types

What Is a Density Meter? We are discussing industrial density meters here, not laboratory densitometers. Industrial density meters are devices specifically designed to measure fluid density, performing real-time online density detection and displaying data such as density and temperature. They also support outputs of 4-20 mA, 0-1000Hz, RS485 Modbus RTU, HART, and other signals, facilitating industrial process control.

Pressure Sensor Selection: Gauge Pressure vs. Sealed Gauge Pressure

Previously, we discussed the differences and relationships between Gauge Pressure and Absolute Pressure. Some users have noticed that when purchasing pressure transmitters, there’s also the option of choosing between sealed gauge pressure and gauge pressure. So, what is the relationship between these two, and how should we choose? Gauge, sealed-gauge and absolute references are all available on our CAN bus pressure transducer with CANopen output.

Hydrogen Flow Meters for Mass and Volume Flow

Hydrogen flow meters are widely used in hydrogen energy fields, such as hydrogen production, hydrogen storage and hydrogen fuel cells. Typically used to monitor volumetric flow, mass flow and usage of hydrogen to ensure proper system operation and optimize performance. Since the value of hydrogen is very high, custody transfer metering is also a very important feature of hydrogen flow measurement.

Sulfuric Acid Storage Tank Level Measurement

In industries such as chemical engineering, metallurgy, pharmaceuticals, electroplating, and sulfuric acid storage and transportation, sulfuric acid, as a basic raw material, is extremely corrosive. 98% concentrated sulfuric acid is viscous, fuming, and easily releases volatile acid mist. Under certain operating conditions, it is also accompanied by complex conditions such as high temperature and crystallization. Therefore, sulfuric acid storage tank level measurement places stringent requirements on the corrosion resistance, stability, and safety of the equipment. Based on our experience at S......
