Updated: April 14, 2026 Flow meter straight length requirements tell you how much undisturbed pipe you need upstream and downstream of the meter. Get this wrong and accuracy drops by 2–5×, regardless of how precise the meter itself is. This Read More
Updated: April 14, 2026 A rotameter is a flow meter, not a separate instrument. It’s one specific type called a variable area flow meter. The real question most engineers ask is: how does a rotameter compare to other flow meter Read More
Updated: April 13, 2026 A diesel fuel tank level gauge measures the amount of fuel remaining in a storage tank or vehicle fuel tank. The right gauge prevents run-dry shutdowns, catches fuel theft early, and keeps inventory records accurate. Choosing Read More
Updated: April 14, 2026 An ultrasonic water level sensor measures water level in tanks, rivers, reservoirs, and wells without touching the water. It’s the go-to choice for clean-water monitoring where a non-contact sensor is required. But it has a blind Read More
Updated: April 13, 2026 An ultrasonic level sensor measures liquid or solid levels by sending a sound pulse and timing the echo. No contact with the media. No moving parts. That makes it one of the most reliable options for 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 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 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 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 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
