2. Instructions for using Anderson six stage sampler
The core of using Anderson six stage sampler lies in precise installation, strict disinfection, and control experimental design.
1. Installation and Preparation 1 Unboxing inspection: The accessories should include standard components such as the main unit, six level impact head, bracket, flow meter, etc. If missing, please contact the manufacturer immediately for replacement. 2. Flow calibration: - When assembling the impact device, hold down the upper part and hang the spring hook, and connect it to the air inlet of the main unit. -Turn on the power supply and adjust the flow adjustment knob to ensure that the flowmeter is stable at 28.3L/min
3. Cleaning and disinfection: - neutral detergent is used to clean the impactor with ultrasonic, and the nozzle is blocked and unblocked with a fine needle or high-pressure air flow. -The surface of the sixth level impactor is disinfected with 70% alcohol. Preparation of sampling petri dishes: - Ordinary agar medium is suitable for routine microbial sampling, and special media should be selected for special microorganisms. -Use sterilized Φ 90x18mm glass petri dishes for future use.
2. Sampling operation gas path connection: Connect the aerosol generator, experimental pipeline, and terminal filter in sequence, place them in a petri dish, and maintain a gas flow rate of 28.3L/min. Set the sampling time to 2 minutes.
. Control experiment: • Negative control: Empty sampling without bacterial suspension for 2 minutes. Positive control: There are two modes: noisy mode A: The dual channel device can simultaneously perform sample testing, grip testing, a
3. What does the specification and model mean in a flowmeter?
It refers to the technical parameters required for selection, such as pipe diameter, temperature, DN20, DN50, etc. FLEXIM ultrasonic flow meter (performance parameters) ⊙ Single channel/dual channel/four channel (optional) ⊙ Flow rate range: 0.01~25 m/s ⊙ Resolution: 0.025 cm/s ⊙ Flow rate accuracy: ± 0.5% ± 0.01m/s of reading ⊙ Volume accuracy: ± 1% ± 0.01m/s of reading (depending on the application) ± 0.5% ± 0.01m/s of reading (after calibration) ⊙ Repeatability: 0.15% ± 0.01m/s of reading ⊙ Power consumption:<15W ⊙ Response time: 1s (1 channel) 70ms optional ⊙ Protection: IP65 (according to EN60529) ⊙ Hazardous area: Zone 2 or Zone 1 (optional) ⊙ Output immunity: current/voltage/frequency/switch quantity (optional) ⊙ Input: Pt100, current/voltage, up to 4 groups ⊙ Medium bridge communication interface: RS232, RS485
4. How to measure water flow without damaging the pipeline
The flow rate of fluid in the pipeline can be detected using a clamp type ultrasonic flowmeter.
. It does not require drilling holes to install detection probes on the tested pipeline, but instead binds the detection probes to the outer wall of the tested pipeline. For installation, the paint on the part of the tested pipeline where the probe is installed should be polished off first, and lithium based diffe
