Molten Salt Flow Measurement: 565°C——How to Select a Flow Meter

Molten salt is not an ordinary liquid; the operating conditions are extremely demanding. Measuring the molten salt flow rate from a storage tank requires simultaneous monitoring of the liquid level, internal tank pressure, and molten salt temperature. The binary solar salt (60% NaNO₃/40% KNO₃) operates at a pressure of 2.5 bar, a flow rate of 36 kg/hr, and a temperature of 565°C. This temperature is very close to the upper decomposition limit for this type of molten salt, requiring special attention.

How Does Gas Composition Affect Thermal Mass Flow Meter Accuracy?

Thermal gas mass flow meters are the preferred instruments for measuring the flow of dry, stable gases—whether pure gases (such as oxygen, compressed air, nitrogen, chlorine, etc.) or gas mixtures (such as biogas). Users often ask us a question during use: Will changing the type of gas being measured or changing the composition of the gas being measured affect the measurement of the thermal gas mass flow meter? The answer is yes. Taking air as the most common example, actual flow tests were performed on a standard calibration rig. Within a flow range of 300–3000 kg/h, variations of 1%, 5%, and......

Liquid Oxygen / Oxygen Pressure Transducer | Cleaned for Oxygen Service (Certificate Included)

Oxygen cleaning is a specialized cleaning procedure for special-purpose pressure transmitters, also known as oil-free. For example, oxygen pressure transmitters must undergo rigorous oxygen-grade cleaning to ensure the sensor is clean and free of oil, corrosion, scale, particles, and other impurities. This completely eliminates the potential risk of oxygen combustion or explosion caused by oil contamination in the sensor during oxygen pressure measurement. Sino-Inst supports customized liquid oxygen to oxygen pressure transmitters and provides Oxygen Clean Certificates. RFQ Table of ContentsCh......

Dynamic vs Kinematic Viscosity

When purchasing an online viscometer, do you often encounter this situation: you specify the viscosity in cSt at 50°C, but the manufacturer provides the value in cP, leaving you confused? Dynamic viscosity (μ) is a fluid’s internal resistance to shear, measured in centipoise (cP = mPa·s). Kinematic viscosity (ν) is that value divided by density, in centistokes (cSt = mm²/s): ν = μ / ρ. Water is about 1 cP and 1 cSt at 20 °C — which is why the two get confused. Most inline viscometers output cP; cSt requires a density input. RFQ Table of ContentsChallenges in molten salt flow measurementF......
