ボルテックス式とタービン式流量計の動作原理ガイド

A vortex flow meter measures flow by counting pressure oscillations created when fluid passes a bluff body — no moving parts, no bearings, no rotor. A turbine flow meter measures flow by spinning a mechanical rotor and counting blade rotations — high precision, but entirely dependent on clean fluid and healthy bearings. That single difference […]
2026年に最適なベンチュリ管式流量計を選ぶためのガイド

To buy the right Venturi tube flow meter, start by defining your fluid type, flow rate range, pipe diameter, operating pressure and temperature, and required accuracy — then match those parameters to a Venturi design that meets ISO 5167-4 specifications for your beta ratio and Reynolds number range. The Venturi meter you select should recover […]
オンライン計算ツールを使って配管の流速を計算する方法

To calculate pipe flow velocity, divide the volumetric flow rate by the pipe’s cross-sectional area. The formula is v = 4Q / πd², where v is velocity (m/s or ft/s), Q is the volumetric flow rate (m³/s or ft³/s), and d is the pipe’s internal diameter (m or ft). In Imperial units, the shortcut is […]
2026年の磁気式流量計の主な用途トップ10

Magnetic flow meters — also called mag meters or electromagnetic flow meters — are the single most deployed flow measurement technology for conductive liquids worldwide. In 2026, the electromagnetic flowmeter market is valued at approximately USD 15.65 billion and growing at a 6.28% CAGR through 2031, according to Mordor Intelligence. That growth is driven by […]
