Nitrogen Flow Controllers for Industrial & Research Applications

Nitrogen Flow Controllers are devices specifically designed for measuring and controlling nitrogen flow. They not only measure the volumetric or mass flow rate of nitrogen, but crucially, they also control the flow rate. Generally, they are based on a nitrogen flow meter, with the addition of an automatic control valve and a closed-loop control system. They can not only measure real-time flow but also automatically and precisely control the valve opening based on user-defined values, stabilizing the actual flow rate at the set value. If you only need nitrogen flow monitoring, please refer to o......

Insertion Flow Meters: 6 Types

Measuring flow in large pipes with insertion type flow meters. If you need to measure the fluid flow of a larger pipe diameter, you are most likely to choose an insertion type flow meter. But what insertion type flow meter should you use? The market has insertion electromagnetic flowmeter, insertion vortex flowmeter, insertion ultrasonic flowmeter, insertion ultrasonic flowmeter and so on. Next, let us compare various insertion type flow meters. Hope to help you choose the right insertion type flow meter!

How to Choose the Right Probe Material for Your Ultrasonic Level Sensor

By Li Rui, Senior Process Engineer at Sino-Inst | Published 2026-03-24. If you’ve ever had an ultrasonic level sensor fail prematurely, there’s a good chance the probe material was wrong for the job. I’ve seen this happen more times than I’d like to admit — a perfectly good sensor, installed in a sulfuric acid tank, corroded within weeks because someone went with the default ABS housing without thinking twice. Choosing the right transducer probe material isn’t glamorous work, but it’s one of those decisions that directly determines whether your level measure......

What is an IP rating? IP65-IP67-IP68

When purchasing pressure transmitters or flow meters, the sales engineer will usually confirm with you what IP rating you need: IP65, IP67, or IP68? This explanation aims to help you understand the details of IP ratings. Next time you purchase electrical equipment, you’ll know which IP rating to choose.

Absolute Pressure Transmitters: Product List and Guide

What is Absolute Pressure Transmitter? Absolute pressure transmitters are sensors that measure pressure using absolute vacuum (0 bar) as a reference. They convert the sensed physical pressure value into a standardized electrical signal, such as 4-20 mA or 0-10 V, for processing by control systems or monitoring equipment. For absolute pressure on a digital bus, see our CAN bus pressure transducer with CANopen and custom CAN 2.0B output. They are often called “industrial barometers” or “technical barometers” because they can measure true, absolute pressure unaffected by e......

Gas Measurements: Normal Conditions vs Standard Conditions

In gas flow measurement and control, it is crucial to distinguish between Normal Conditions and Standard Conditions. This is primarily because the volume of gas changes with temperature and pressure. Different standards will result in different measured gas values. This is somewhat similar to the difference between “SCFM (Standard CFM) and ACFM (Actual CFM)“.

SCFM (Standard CFM) vs. ACFM (Actual CFM) and Calculator

SCFM (Standard CFM) and ACFM (Actual CFM) are commonly used units for measuring gas flow rate. For example, in the air compressor industry, they are used to measure airflow and air consumption. So what are the differences between them? How should they be converted?
