Buyer’s Guide: 7 Checks for Selecting a Variable Area Flow Meter

The selection of an appropriate variable area flow meter, commonly known as a rotameter, represents a foundational decision in numerous industrial and laboratory settings. This process demands a nuanced consideration of multiple interacting factors, extending beyond simple flow rate measurement. These include the density, viscosity, and corrosiveness of the medium and their direct impact on meter performance and life. The pipe diameter, the required flow range, the pipe temperature, and the pressure, among other factors, must be considered systematically. By systematically considering these co......

Static Torque vs Dynamic Torque: A Practical Guide to Selecting the Right Sensor in 2026

The distinction between static and dynamic torque represents a fundamental division in the field of mechanical measurement and engineering. Static torque, often termed reaction torque, pertains to the rotational force applied to an object that does not produce angular acceleration. It is the force of twisting or turning against a fixed resistance. Conversely, dynamic torque involves the measurement of rotational force on a moving or rotating component, such as a driveshaft or motor. The accurate quantification of these forces is paramount across numerous industries, from automotive engineering......

Case Study: Custom Thermal Mass Flow Meter For Nitrogen Flow Measurement

Thermal mass flow meters are widely used to measure gas flow in industrial processes. They determine the mass flow rate by measuring the thermal changes in the fluid as it flows through the sensor. Sino-Inst’s thermal mass flow meters utilize a unique temperature differential measurement method to overcome the drawback of traditional thermal mass flow meters that use a constant temperature differential principle. These meters, when measuring gas flow, suffer from significant zero-point drift caused by water, oil, and impurities in the gas, leading to measurement failures. Customization C......

Pressure Transmitter 4-20mA Guide: Testing and Troubleshooting

What is a pressure transmitter 4-20mA? A 4-20mA pressure transmitter is an instrument that measures medium pressure and converts it into a 4-20mA current output signal. In industrial processes, the most common method for transmitting analog signals is using a 4-20mA current loop. The signal is transmitted to a remote control panel for pressure monitoring and control. For example, this can involve audible and visual alarms or initiating certain trip and shutdown procedures. In a 4-20mA pressure transmitter, the 4-20mA output is linearly proportional to the pressure range. 4mA corresponds to a z......
