What Is a Density Meter? And Guide to Types

What Is a Density Meter? We are discussing industrial density meters here, not laboratory densitometers. Industrial density meters are devices specifically designed to measure fluid density, performing real-time online density detection and displaying data such as density and temperature. They also support outputs of 4-20 mA, 0-1000Hz, RS485 Modbus RTU, HART, and other signals, facilitating industrial process control.

Pressure Sensor Selection: Gauge Pressure vs. Sealed Gauge Pressure

Previously, we discussed the differences and relationships between Gauge Pressure and Absolute Pressure. Some users have noticed that when purchasing pressure transmitters, there’s also the option of choosing between sealed gauge pressure and gauge pressure. So, what is the relationship between these two, and how should we choose? Gauge, sealed-gauge and absolute references are all available on our CAN bus pressure transducer with CANopen output.

Hydrogen Flow Meters for Mass and Volume Flow

Hydrogen flow meters are widely used in hydrogen energy fields, such as hydrogen production, hydrogen storage and hydrogen fuel cells. Typically used to monitor volumetric flow, mass flow and usage of hydrogen to ensure proper system operation and optimize performance. Since the value of hydrogen is very high, custody transfer metering is also a very important feature of hydrogen flow measurement.

Sulfuric Acid Storage Tank Level Measurement

In industries such as chemical engineering, metallurgy, pharmaceuticals, electroplating, and sulfuric acid storage and transportation, sulfuric acid, as a basic raw material, is extremely corrosive. 98% concentrated sulfuric acid is viscous, fuming, and easily releases volatile acid mist. Under certain operating conditions, it is also accompanied by complex conditions such as high temperature and crystallization. Therefore, sulfuric acid storage tank level measurement places stringent requirements on the corrosion resistance, stability, and safety of the equipment. Based on our experience at S......

Case: Non-Contact Ultrasonic Flow Meter For Water

A clamp-on ultrasonic flow meter is an instrument that uses high-precision ultrasonic sensing technology to measure flow rate. It mainly consists of a host and a set of ultrasonic sensors. These sensors can be installed on the outer wall of the pipe without the pipe or shutting down the system, and they will not contaminate the medium in the pipe. The clamp-on ultrasonic flow meter measures the velocity and flow rate of fluids by utilizing the propagation characteristics of ultrasonic waves. It has advantages such as being non-invasive, highly accurate, and widely applicable. Custom Case A cli......

Thermal Dispersion Flow Switches: A Complete Guide

A thermal diffusion flow switch is a flow monitoring device based on the principle of thermal diffusion. It offers superior performance and reliability. Thermal diffusion flow switches have no moving parts. They are durable, have low maintenance costs, and are highly reliable. We, Sino-inst, offer the SI-300C and SI-600 series of thermal diffusion flow switches. They can output PNP, NPN, relay, and normally open + normally closed (SPDT) signals. This article will provide a detailed overview of thermal diffusion flow switches. RFQ Table of ContentsWhat Is a Density Meter?Why is density monitori......

Top 10 Pressure Transmitter Terminology

Behind every aspect of industrial process monitoring and control lies an indispensable “invisible hero”—the pressure transmitter. The performance of a pressure transmitter determines safe operation and production efficiency. Chemical plants rely on pressure transmitters to prevent pipeline leaks, and automobile manufacturing depends on hydraulic systems for precise control of robotic arms. However, the densely packed specifications on pressure transmitter datasheets, such as “range 0-1MPa” and “accuracy ±0.1% FS,” can leave you confused about which to choose......
