Electronic soap film flow meter

DAL-1 electronic soap film flow meter

Introduction

The electronic soap film flow meter is a device used to measure gas flow. It calculates the gas flow by measuring the time it takes for the film formed by soap liquid to pass through a certain volume of glass tube. The DAL-1 electronic soap film flow meter measures time and calculates flow rate through its internal microprocessor and photoelectric components, and displays it intuitively on the screen. Its accuracy is much better than indirect judgment by holding a stopwatch with your eyes and hands. This instrument is easy and reliable to operate, has clear display, has its own advantages in structure and good cost performance.

Main performance indicators:

• Four-digit digital display can display battery voltage, time, flow, etc.;

• Measurement accuracy: △Q<±1%;

• Measuring range: 5~900ml/min;

• Built-in rechargeable battery, working time >30hr after full charge;

• Connect an external 9V DC power supply and charge the battery through the internal charging circuit. The charging time is 10-20 hours;

• Overall dimensions: approximately 120*95*260mm.
