BS-YDigital gas flow meters are widely used in fields such as environmental monitoring, health and epidemic prevention, industrial and mining enterprises, scientific research and teaching, labor safety, and food.

characteristic:
1.Within the required environmental conditions, display the standard state (temperature:0℃, atmospheric pressure:101.3KpaOr temperature:20℃, atmospheric pressure:101.3KpaThe traffic can be customized by the user.
2.The use of high-precision electronic flow devices for flow digital display greatly improves the accuracy of gas flow acquisition.
3.Adapt to different gas flow displays, such asAir、N2、NO、N2O、CO2Wait.
4.Dual use of AC and DC, suitable for different work environments.
5.This instrument is small in size, light in weight, and easy to operate.

correcting：
When using a soap film flowmeter for gas flow calibration, due to the influence of temperature and atmospheric pressure on the displayed flow rate of the soap film flowmeter, while this instrument displays the standard flow rate under standard conditions, the flow rate of the soap film flowmeter should be converted to the flow rate under standard conditions during calibration. As an example, the standard condition is (temperature:0℃, atmospheric pressure:101.3Kpa）：

Repair and maintenance：
1High precision electronic components are used inside the instrument. During transportation, storage, and use, care should be taken not to collide to avoid affecting measurement accuracy and service life.
2The instrument belongs to intelligent measuring instruments, and attention should be paid to moisture, mold, and corrosion prevention during storage and use.
3The large-scale integrated circuit of the instrument adoptsCMOSComponents should avoid damage from electromagnetic fields, microwave radiation, and high-frequency electric sparks.
4The instrument should use LCD display and avoid direct sunlight to prevent aging.
5The instrument is covered by a one-year warranty. If used improperly or damaged by human factors, our factory is responsible for maintenance and only charges for parts.
6Due to the fact that the instrument is a precision electronic instrument, if any malfunction is found during use, the user should send it to our company's maintenance department for repair. Do not disassemble it without authorization to avoid expanding the scope of the malfunction. If the user disassembles and repairs it themselves, our company will not be responsible.
matters needing attention：
1Due to the use of high-precision electronic components inside this instrument, the following situations are strictly prohibited during use:
①Water ingress;
②Do not use a filter for the air intake during use;
③Regularly do not replace the filter (the replacement cycle is generally15Days of use);
2When the battery is low, the instrument will automatically operate“LOB”Reminder: In this state, external AC power can be used to continue or charged in a timely manner.
3The operator should try to maintain the charging time of this instrument as long as possible6--8Between hours to ensure the battery's lifespan.
