Updated: April 11, 2026 A flow totalizer and a flow meter serve different purposes, though the terms are often used interchangeably. A flow meter measures instantaneous flow rate—how fast fluid is moving right now. A flow totalizer accumulates that flow Read More
Updated: April 11, 2026 A BTU meter measures the thermal energy transferred in a heating or cooling system. It combines a flow sensor with a pair of temperature sensors and a calculator to determine how many BTUs (British Thermal Units) Read More
Updated: April 10, 2026 A pressure sensor converts mechanical pressure into an electrical signal. It is the sensing element inside every pressure transmitter, transducer, and switch used in industrial process control. The electrical output—typically a change in resistance, capacitance, or Read More
Updated: April 10, 2026 Flow meter calibration is the process of comparing a meter’s output against a traceable reference standard and adjusting it to minimize measurement error. Every flow meter drifts over time due to wear, fouling, or process changes. Read More
Updated: April 10, 2026 Class 1 Div 1 and Class 1 Div 2 are two NEC hazardous location classifications that define how likely flammable gases or vapors are to be present. The distinction matters because it determines what type of Read More
Updated April 2026 — By Sino-Inst Engineering Team Flow rate and pressure are the two most measured variables in any piping system. They are connected, but not in a simple linear way. Pressure difference drives flow. No pressure difference, no Read More
Updated April 2026 — By Sino-Inst Engineering Team Wiring a pressure transducer correctly is the difference between a clean 4–20 mA signal and hours of troubleshooting. The three wiring configurations — 2-wire, 3-wire, and 4-wire — each have different power Read More
Updated April 2026 — By Sino-Inst Engineering Team A pressure transmitter converts the mechanical force of fluid or gas pressure into an electrical signal — typically 4–20 mA or a digital protocol like HART. That signal goes to a PLC, Read More
Sino-Inst offers a variety of HART pressure transmitters for industrial pressure measurement. If you have any questions, please contact our sales engineers. What is hART in a pressure transmitter? The HART protocol is a backward-compatible smart instrument solution for the Read More
Magmeter flow meter guide covering working principle, selection, specs, installation advantages, and Sino-Inst electromagnetic solutions. What is a Magmeter Flow Meter? Magmeter Flow Meters are also called Electromagnetic flow meters or magnetic meters. Magmeter Flow Meter is a type of Read More
