Brewing & Dairy: How Food-Grade EMFs Prevent Contamination
One stray metal particle can ruin an entire batch of milk or beer. Food-grade electromagnetic flow meters provide critical protection. Food-grade EMFs use FDA-approved materials (PTFE liners, 316L SS electrodes) and hygienic connections to prevent contamination. Their smooth surfaces and crevice-free designs eliminate bacterial traps, while metallic detection systems alert to any abnormal particles in […]
Non-Full Pipe Flow: Can EMFs Measure It?
Flow measurement fails when pipes aren’t full. But why does this happen, and what are your alternatives? EMFs require full pipe conditions to work accurately because they measure voltage induced across the liquid’s cross-sectional area. When pipes aren’t full, the signal corresponds only to the wetted electrode portion, causing 30-50% errors. Only specially designed "partial-full" […]
Electrode Materials Face-Off: Titanium vs. Hastelloy vs. Platinum
Choosing the wrong electrode material can lead to costly flowmeter failures in corrosive environments. Understanding these three premium materials prevents measurement disasters. Platinum electrodes excel in oxidating acids but cost 10× more than alternatives. Hastelloy C276 handles reducing acids better than titanium, while titanium Gr2 offers the best price/performance for chlorine environments. Material selection depends […]
The Truth About EMF Accuracy: Why ±0.5% Claims Aren’t Always Realistic
Manufacturers proudly advertise ±0.5% accuracy for electromagnetic flowmeters (EMFs), but field technicians know reality often differs. What really determines your magmeter’s actual performance? True EMF accuracy requires perfect installation conditions: full pipes with symmetric flow profiles, adequate conductivity (>5 μS/cm), and proper grounding. While lab tests may achieve 0.5% under ideal circumstances, field conditions typically […]
How Electromagnetic Flowmeters Work: Faraday’s Law in Action
Installing the wrong flow measurement system can lead to costly miscalculations. Understanding Faraday’s Law helps select the perfect magmeter for conductive fluid applications. Electromagnetic flowmeters operate using Faraday’s Law of Induction – when conductive fluid flows through a magnetic field, it generates a voltage perpendicular to both flow and field directions. This induced EMF (electromotive […]
What is the Difference Between Magnetic Flow Meter and Vortex Flow Meter?
Choosing the wrong flow meter can cost thousands in wasted materials or inaccurate billing. The key is knowing which technology fits your specific fluid and conditions.

Why Does A Magnetic Flow Meter Need Grounding?
Your mag meter suddenly shows erratic readings – did you check the grounding? Poor grounding causes 50% of all mag meter failures in the field.

What Is the Measuring Range of Electromagnetic Flow Meter?
Struggling to select the right mag meter size? The secret lies in matching pipe flow rates – not just pipe diameter. Standard electromagnetic flow meters measure 0.3-10 m/s velocity (0.98-32.8 ft/s), with actual flow range determined by pipe size. For a DN100 (4") pipe, this equals 8.5-850 m³/h (50-5000 GPM). Measurement accuracy degrades below 0.3 […]
