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......

Ultrasonic Flow Meter for Water and Other Liquids

An ultrasonic liquid flow meter is a non-contact flow measurement instrument. It uses ultrasonic waves to measure the velocity of a given fluid or gas. It calculates the flow rate by detecting the difference in forward and reverse sound wave propagation. It has no pressure loss and is widely applicable. It is widely used in various fluid and gas applications. Currently, there are two types of ultrasonic flow meter technologies: Doppler and transit time. In this article, we will mainly introduce and analyze the ultrasonic liquid flow meter used to measure liquids. Ultrasonic liquid fl......

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......

Understanding RTD Sensors: Key to Measure Industrial Temperature

“RTD” stands for “resistance temperature detector.” It is a type of temperature sensor. And it uses the electrical resistance of metal to measure temperature. RTDs offer high accuracy and stability. But they are more expensive than other sensors, such as thermocouples. They are widely used in various industries, including automotive, aviation, and food processing. The sensing element of an RTD sensor is typically made of platinum, copper, or nickel. The temperature range is -196°C to 600°C. Some special designs can even reach 1000°C. At Sino-Inst, we primarily offer thr......
