When selecting a steam flowmeter, these technical details deserve your attention

Do you know which details you need to check when selecting a steam flowmeter? The editor has compiled a series of contents here, hoping to help you solve the selection problem. Follow the editor to see what needs to be paid attention to; when selecting a steam flowmeter, not only should you pay attention to the measurement principle and measurement of the steam flowmeter Parameters such as accuracy are also worthy of special attention in the following technical details:

(1) For the standard orifice steam flowmeter, while meeting the measurement accuracy, reduce the pressure loss at the steam flowmeter as much as possible. In the design, the opening diameter of the orifice plate should be determined as large as possible to reduce the pressure loss.

(2) For equipment such as steam pipelines that cannot be shut down for a short period of time once they are in operation, an all-welded steam flow meter should be selected as much as possible. A company's steam pipeline used a flange-clamped nozzle steam flowmeter. After many years of operation, due to long-term thermal deformation or gasket damage, the steam flowmeter's clamping ring leaked slightly. greater economic losses.

(3) The straight pipe sections before and after the steam flowmeter should be as long as possible. If it is impossible to find an installation location for a long enough straight pipe section, consider using a beam conditioner.

(4) The power supply of the steam flow computer is recommended to be considered according to the particularly important load in the primary load. The 2-channel DC power modules are powered by one UPS and one city power respectively. The output of the 2-way DC module is introduced into the steam flow computer through the redundant module.

(5) Before ordering the steam flowmeter, the process pipeline and automatic control instrument professionals should be organized to review and confirm the size and material of the pipeline. It is best to open the insulation to measure the outer diameter of the pipe. Avoid the inconsistency between the size of the steam flowmeter and the pipeline due to incomplete data preservation in the early years.

(6) When the agreement is signed, it is recommended to agree with the equipment manufacturer to provide the supervision and inspection certificate issued by the qualified power station boiler inspection agency.

(7) The strength of the thermowell shall be calculated and verified according to ASME PTC 19.3 TW-2016 "Thermowells Performance Test Codes".
