Gabay sa Pagpili ng Flowmeter

Paano pumili sa pagitan ng electromagnetic, vortex, thermal mass, at differential-pressure flowmeter — at alin sa aming mga model ang babagay sa iyong medium, range, at accuracy.

Hakbang 1 · Kilalanin ang iyong likido

I-match ang technology sa medium

Ang unang tanong ay laging: ano ang sinusukat mo, at ano ang kailangan mo sa pagsukat?

TechnologyBest forKey limitsModels
Electromagnetic Conductive liquids (≥1–5 uS/cm), water & wastewater, slurries, clean water Cannot measure gases, steam, or non-conductive liquids SE11E · SE10A · SE11H · SE13E · SEB600S
Vortex Steam, gas, and liquid — one meter for all three; low maintenance Accuracy affected by vibration; needs reasonable flow velocity SV21 · SV23 · SVH
Thermal mass Direct gas mass flow — no separate temperature/pressure compensation Gas applications only; not for liquids ST51 · ST54
Differential pressure Budget large-pipe measurement, high-temp/high-pressure, dirty or viscous media Lower accuracy, higher permanent pressure loss (except SD41/SD42) SD40 · SD41 · SD42 · SD43 · SD45
Variable area (rotameter) Simple, cost-effective local indication of liquid/gas/steam flow Manual reading; needs transparent line or indicator SR41
Hakbang 2 · I-check ang pipe & range

I-match ang size at accuracy sa line

Kapag alam mo na ang technology, ang natitirang desisyon ay pipe size, accuracy class, at process conditions.

SVHVortex (digital)DN15–300liq ±0.75% · gas ±1.0%-40~260°C
ST51Thermal massflange/thread/insert±1.0% (gas mass)up to 100:1 turndown

Quick rule of thumb: conductive liquid → electromagnetic (SE11E for accuracy, SEB600S for no-power field sites). Steam/gas, one meter for all three phases → vortex (SV21). Direct gas mass flow → thermal (ST51/ST54). Budget, dirty, or large-line → differential pressure (SD41 balanced is the accuracy pick).
