Updated: April 11, 2026 A venturi tube is a differential pressure device used to measure the flow rate of fluids in a pipe. It works on a simple principle: force fluid through a constriction, measure the pressure drop, and calculate Read More
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 For the parallel calibration discipline on rotating instruments (shaft torque sensors), see our shaft torque sensor guide covering re-zero, re-cal, and replace thresholds. Flow meter calibration is the process of comparing a meter’s output against a 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 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
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
Leading turbine flow meter manufacturer Sino-Inst offers high-accuracy liquid and gas meters with wide turndown and ISO certified performance. As a manufacturer, We prioritize mechanical precision because the turbine flow meter principle relies on a simple yet highly effective law Read More
