H₂O₂ Concentration Meter Inline
Working Principle
The built-in H2O2 concentration sensor utilizes the direct correlation between salinity concentration and liquid density. The continuous h2o2 monitor is excited by a piezoelectric tuning fork to vibrate at its natural frequency. Fluid density is in inversely proportion to frequency shift. The greater the density, the more mass the tines have to vibrate, and the lower their frequency becomes. It's applicable to monitor salt content before crystallization in chemical engineering in case a high precision and accuracy is required. It excels in long-term stable monitoring with an accuracy of ±0.2% even in corrosive media.
Product Features
● Real-time density measurement for direct integration into process control systems;
● Enables density-to-concentration conversion across all media types;
● Delivers high-precision 5-digit real-time readings (with 4 decimal places);
● Converts measured density data to 4-20mA analog signals or RS485 digital signals;
● Supports on-site parameter configuration and commissioning;
● Offers customizable materials for wetted components, tailored to corrosive media;

Challenges in Continuous H₂O₂ Concentration Measurement
● Temperature fluctuations alter H₂O₂ density and cause concentration reading deviations;
● High/low flow rates lead to uneven liquid-sensor contact or delayed liquid renewal;
● Bubbles reduce local liquid density, interfering with accurate H₂O₂ concentration calculation.
● Fouling and sedimentation corrode the core sensor, shortening its lifespan and undermining continuous measurement stability.
Advantages of Lonnmeter Continuous H₂O₂ Meter
● Automatic Temperature Compensation (ATM) minimizes interference from temperature-induced density changes;
● Selectable corrosion-resistant Materials prevents core sensor degradation from fouling/sedimentation;
● Fully encapsulated design eliminates sensor exposure to corrosive H₂O₂-containing media;
● Simple mechanical structure reduces the need for frequent maintenance and replacement;
● Explosion-Proof design enhances the device’s safety grade for hazardous environments;
● Automatic data logging & documentation enables real-time process adjustment and data analysis;
