1. What are the types of mass flow meters?

2. What are the installation requirements for mass flow meters? Does the installation of mass flow meters require a straight pipe section?

The installation requirements for mass flow meters mainly include the following points: stay away from strong electromagnetic fields: the installation position should be away from equipment that may generate strong electromagnetic fields, in order to reduce the impact of electromagnetic interference on measurement results.. Consistent flow direction identification: The sensor flow direction identification should be consistent with the fluid flow direction, with the arrow pointing in the same direction as the flow direction configured inside the transmitter. If the direction is opposite, adjust the flow direction setting inside the transmitter. Reduce vibration impact: When installing sensors, sturdy supports should be provided near the flanges of the process pipelines on both sides. If necessary, flexible pipes should be used to isolate the pipeline system from the sensors. Maintain the position of the measuring tube: Due to the principle of Coriolis force, the measuring tube should be kept as vertical or horizontal as possible to avoid gravity interference. During installation, the flange faces should be parallel to ensure that the centers of the two flanges are on the same axis. Installation of valves and bypasses: It is recommended to install shut-off valves and bypasses in the upstream and downstream pipelines of the sensor to facilitate zero adjustment, maintenance, and ensure that the sensor remains in a fully tubular state when not in operation. Ensure that the medium is fully filled: The installation direction

of the sensor should ensure that the medium is completely filled to avoid gas accumulation or liquid gas gathering. Pipeline blowing: Newly installed pipelines or pipelines that have not been used for a long time must be thoroughly blown before installing a mass flow meter to remove welding slag or debris and ensure measurement accuracy. Install filter: It is recommended to add a filter at the inlet of the flowmeter and choose the appropriate installation direction of the measuring tube according to the different measuring media. Quality flow meters do not need to consider straight pipe requirements. Since the flow rate is independent of the mass flow meter, the necessity of straight pipe sections is completely eliminated, so there is no need to worry about the impact of straight pipe sections on measurement accuracy.

3. Piping Regulations for Flowmeters

Piping Regulations for Flowmeters: Flowmeters are used in petrochemical plants to measure the flow of fluid in pipelines, and their piping design must comply with the following regulations:

1. General Provisions This regulation applies to the installation design of flow meters for measuring fluid flow in pipelines in petrochemical plants.

. Including the installation design of differential pressure flow meters (orifice plate, nozzle, Venturi tube, internal orifice plate type), volumetric flow meters (elliptical gear), area flow meters (rotor flow meters), turbine flow meters (gas turbine, liquid turbine), and vortex street flow meters (compensating type, pressure type, differential pressure vortex street). In addition to complying with this regulation, the piping design of flow meters must also comply with relevant piping material grade design reg
