Rotameters: Excellent Choice for Flow Measurement in Various Gases

A rotameter, also known as a variable area flow meter, is widely used to measure the flow rate of various gases, especially in situations where no power supply is available. Whether measuring air, oxygen, nitrogen, carbon dioxide (CO2), or other gases, rotameters provide reliable and accurate results. Of course, rotameters can also be configured as electronic smart devices, providing local digital display and outputs such as 4-20mA and switch signals. This has led to rotameters occupying a larger share of the industrial gas flow measurement market. RFQ Table of ContentsTo begin with: What is a......

4 Types of Manifolds for Pressure Transmitters

Pressure transmitters are often installed in conjunction with manifolds, primarily for isolation, calibration, and venting. Manifolds control the input of the medium, ensuring measurement accuracy and safety. Manifolds are typically configured with a specified number of valves based on the required operating conditions. Common configurations include single-valve (2-valve), two-valve, three-valve, and five-valve manifolds. When purchasing pressure transmitters or differential pressure transmitters, you can inform us of the type of manifolds you require. RFQ Table of ContentsTo begin with: What ......

Industrial Water Pressure Measurement and Monitoring

Water pressure measurement includes pressure detection of water pipes, water containers or equipment. Water pressure measurements can be used to determine whether a pipe, container or equipment is leaking and whether it can withstand the pressure required for the design. By configuring a water pressure transmitter, connecting the water pressure signal to a recorder, PLC and other systems, or configuring a wireless signal, you can build a remote water pressure monitoring system.

Choose Digital Water Pressure Switch for Better Control

A water pressure switch is a device used to monitor and control the pressure of a water system. Commonly found in domestic and industrial water treatment systems, it is used to start or stop water pumps and ensure that the water pressure remains within a set range. A digital water pressure switch can display the water pressure value in real time and allows users to manually set the upper and lower limit switching points. Therefore, digital water pressure switches have a wider range of applications. RFQ Featured Digital Water Pressure Switches Explosion Proof Pressure Switch | 2, 4, 5-Point Con......

Case Study – Mass Flow Meter For Slurry

In industrial production, since material balance, storage, and economic accounting all require mass rather than volume, measurement work often involves converting the measured volumetric flow rate into mass flow rate by multiplying it by the density. For example, in mining production, we often need to calculate the flow rate of mineral slurry. Mineral slurry refers to a two-phase solid-liquid suspension system formed by mixing solid ore particles with water (or liquid). However, because of unstable factors in the slurry, such as air bubbles and concentration changes, the volumetric flow r......
