YFLJZ standard nozzle flowmeter is also known as ISA1932 nozzle. It has the characteristics of high temperature and pressure resistance, impact resistance, long service life, large measurement range and high measurement accuracy. Standard nozzles are designed and manufactured according to international GB / T2624.1-2006, and verified according to JJG640-94. No live calibration is required.
Product advantages:
1. Most suitable for measuring high temperature steam flow measurement
2. Relevant national standards, no actual flow calibration required
3. Pressure loss is better than orifice flowmeter
4. Measurement accuracy is better than 1.0
