Soap film flow meter for gas volume using high-precision timing system, whether it is a small flow such as 0.1mL/min or a large flow of up to 30L/min, this volume flow meter can run stably, time resolution up to 0.001s, wide measurement range, suitable for all kinds of gas media, with rechargeable batteries, strong endurance, energy saving and durable.

Specification

Feature

1. Provide 1 to 6 Ranges: Accurately determine the volume flow rate of gas, adapt to a variety of testing needs.
2. Failure Self-detection: Measure the gas flow rate by combining the circuit control unit inside the volume flow meter and the sensitive element, with the function of failure self-detection and automatic adjustment, without the need for personnel adjustment.
3. Built-in Auto Adjustment System: Intelligent adjustment of measurement parameters according to the flow rate changes, more convenient operation.
4. Support Gas Conversion Function: Convenient for data conversion and comparison between different standards.

Application

Tips:  Soap film flow meter for gas volume introduction

RDDLZ-HM series soap film flowmeter is used to determine the volume flow of gas, belongs to the first-class flowmeter, the accuracy is better than ±1%. This series of volume flow meter consists of microcontroller, infrared sensor, pre-circuit, driving circuit, keypad, display, power supply and other parts, through its internal circuit control unit and sensitive components to measure gas flow, with fault self-testing and automatic adjustment function, no need for personnel adjustment.

Built-in conversion function, can carry out the conversion of work sinking flow rate and standard flow rate. Gas flow rate can be measured for a single time, or the average value can be taken after several measurements (the number of measurements can be set). It is often used for flow measurement and calibration of atmospheric sampler, dust sampler, gas chromatograph, rotor flowmeter, orifice flowmeter, mass flowmeter and so on.
