Gas Flow Controller - Chemical and Common Standardization Instruments

Product SummaryIntroduction:

The PTTC-GC3 gas flow controller is based on JJG 693-2011 "Combustible Gas Detection Alarm" and JJG 365-2008 JJG 635-2004、JJG 678-2007、JJG 915-2017、JJG 1022-2007、JJG 1077-2012、JJG Measuring instruments developed according to relevant metrological verification regulations such as 1105-2015 and JJG 1433-2013, whose performance meets the requirements of relevant metrological verification regulations, are used to control the flow rate of gas during the calibration or verification of gas detection alarms. PTTC-GC3 type belongs to intrinsic safety measuring equipment; Due to the adoption of a new design, there is no need for packaging box protection, small size, light weight, easy to carry, and suitable for on-site inspection or calibration.

[Instructions for Use]

1. Connect the standard gas to the standard gas port; Connect the calibration port to the device being tested (calibration cover or pump suction combustible gas alarm).

2. Open the standard gas pressure reducing valve and control the output gas pressure atBetween 0.05MPa and 0.2MPa.

3. Adjust the flow control valve of the vent flowmeter to ensure that the flowmeter is at an appropriate reading; adjustCalibrate the flow control valve of the flowmeter to ensure that the calibrated flow meets the requirements for calibration or combustible gas alarmWork requirements, start working.

4. Work completed, close the standard gas pressure reducing valve.

【Precautions:

1. When using a flowmeter, the flow control valve should be slowly opened to prevent the float from suddenly impacting upwards and damaging the glass canal.

2. Must maintainPTTC-RQ2Clean and prevent dust from entering the flow meter“freeze”Float,Causing equipment damage.

3. The input gas source pressure shall not exceed 0.3MPa.

4. Generally, calibration or calibration of flow meters and vent flow meters is carried out every two years, and the accuracy level of the flow meters is better than4.0 Grade.

5. For the convenience of on-site use by users, PTTC-RQ2 The standard configuration is a pagoda shaped interface; If other special interfaces are required, please specify the relevant requirements in the Product Purchase and Sales Contract.

6. Float flowmeter is a precision instrument. IfPTTC-RQ2If there is a malfunction, our company will take actionProvide free maintenance services; Only the replacement parts fee will be charged if the warranty period is exceeded.

The measuring instrument developed according to JJG 693-2011 "Combustible Gas Detection Alarm" meets the requirements of JJG 693 in terms of performance and is used in places where gas flow needs to be controlled, such as calibration or verification of combustible gas alarms.
