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 … Read more

7 Types of Biogas Flow Meters – 9 Steps to Select the Right One

Biogas is a form of clean energy, primarily composed of methane (CH4) and carbon dioxide (CO2). In the fields of renewable energy, environmental protection, and energy management, biogas flow measurement is a critical step in ensuring accuracy during production, utilization, and trade. This article outlines the various types of biogas flow meters and provides guidance … Read more

Miniature Multipoint Thermocouple Probe– Type K

The iTCMM mini-multipoint thermocouple probe is a Type K device capable of providing up to 30 measurement points within a 6 mm diameter probe sheath. Fine chemical reaction processes often utilize shell-and-tube reactors (fixed-bed reactors); the internal space within the reactor tubes is confined, yet a high number of measurement points is required to ensure … Read more

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 … Read more

Foam Level Sensor – Detection and Control

Fermentation industries—such as those involved in antibiotic production—generate significant amounts of foam. Excessive foam can overflow, leading to product loss and microbial contamination. To address this, foam levels must be continuously monitored, and appropriate amounts of antifoam agent automatically dispensed when necessary to maintain control. Our Foam Level Sensors are designed specifically for this purpose: … Read more

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, … Read more

Ultrasonic Open-Channel Flow Meter

The CS-3300 series Ultrasonic Open-Channel Flow Meter is used together with a measuring weir or flume to measure the flow of water in an open channel. It is mainly used for sewage-treatment plants, the sewage-discharge outlets of enterprises and institutions, urban sewers, and irrigation channels in farmland water-conservancy projects. It can directly display instantaneous flow … Read more

Open Channel Flow Meters

What is an open channel flow meter? Open channel flow meters are primarily used to measure liquid flow rates in open channels. Common applications include agricultural irrigation, municipal sewers, rivers, drainage channels, and wastewater treatment plants. These meters directly measure the water level and flow velocity in the channel to calculate the flow rate. They … Read more

Radar Flow Meter

The radar flow meter is a compact, non-contact, online monitoring device designed for applications such as open channels and natural rivers. It operates based on the Doppler effect: electromagnetic waves are transmitted toward the water surface and scatter upon contact with the moving water, generating an echo. Because the frequency of the received echo shifts … Read more

Ultrasonic Doppler Flow Meter

This Doppler ultrasonic flow meter utilizes the ultrasonic Doppler principle to measure flow velocity and flow rate in open channels. A submersible ultrasonic sensor is installed at the bottom of the channel; the measurement point is located in front of the probe, ensuring the flow field remains undisturbed. It continuously monitors flow velocity and water … Read more
