1、 Overview
The ZM-100B series portable electronic soap film flowmeter is the latest updated product launched by our company based on the GL-100B series flowmeter. It is suitable for detecting the flow rate of any gas or liquid and is an essential instrument for calibrating medium and small gas flowmeters in environmental protection, labor hygiene, scientific research, industrial and mining, various universities and other departments. Users can measure gas or liquid flow rates ranging from 0.1ml/min to 30L/min by selecting instruments with different ranges. The instrument has calibration functions for temperature, pressure, and volume, and users can calibrate it themselves, fully meeting the JJG 586-2006 "Verification Regulations for Soap Membrane Flowmeters". The ZM-100B series portable electronic soap film flowmeter is mainly used for:
Measurement and calibration of atmospheric sampler flow rate;
Measurement and calibration of dust sampler flow rate;
Measurement and calibration of carrier gas and auxiliary gas flow rate in gas chromatography;
Measurement and calibration of rotor flowmeter;
Measurement and calibration of orifice flow meters;
Measurement and calibration of flow rate using LCR tester;
Measurement and calibration of flow rate of flue gas sampler.
2、 Main performance characteristics:
★ Microcomputer program control, automatic data processing, can fully display information such as air pressure, temperature, volume, time, flow rate (including volume flow rate and mass flow rate), upper and lower sensor status, etc
★ Fault self check, which can simultaneously measure the luminous flux of the upper and lower sensors. Users can adjust the resistance of the internal potentiometer to achieve optimal sensitivity.
★ Real time monitoring of battery power and display of instrument power real-time indication charging information.
★ It integrates sensors, soap film tubes, and circuit systems, with small size, light weight, and easy portability.
★ Measurement accuracy: △ Q ＜ ± 1%
★ Repeatability: ＜ 0.5%
★ Flow accuracy: 0.1ml/min
Time accuracy: 0.1S (internal calculation accurate to 0.01S).
★ Nominal range: 30ml/min~30000ml/min
★ Equipped with a rechargeable battery with a nominal value of 4.8V/700mA/h, it can stand by for more than 24 hours after being fully charged, and can be charged more than 500 times
★ External 9V DC power supply. When the battery is depleted, this power supply can be plugged into the back panel of the flowmeter for replacement use. At the same time, the battery is charged through an internal charging circuit. After the instrument is charged, it automatically enters a float charging state and is fully charged in about 8 hours.
★ Implement energy-saving concept, stop operation within 1 minute, turn off the backlight of the display screen, and automatically shut down if there is no operation within 5 minutes, achieving energy-saving management
★ Dimensions: 90mm × 150mm × 280mm
★ Weight: Approximately 2.3kg
