Inquiry (采购产品): Sonic nozzles Dear Sir or Madam, We need to buy a series of sonic nozzles to cover the following flow rate range: For air, the desired flow rate ranges from 100 cc/s up to 2500 cc/s. For propane, the desired flow rate ranges from 10 cc/s up to 150 cc/s Here are the pressure information: For air, the gauge pressure ranges between 20 Psig to 70 Psig For Propane, the gauge pressure ranges between 20 Psig to 50 Psig Based on the above information, can you please let me know: How many sonic nozzles do we need to cover this flow rate range according to the air pressure gauge range indicated above? How many sonic nozzles do we need to cover this flow rate range according to the propane pressure gauge range indicated above? How much does it cost for us to them? How long is the lead time? In term of calibration, the accuracy of ±2% even ±5% is good for us. Also, how much does it cost to calibrate all of them and how long will it take?
