Product details

The intelligent elbow flow meter is a differential pressure flow measurement system. The elbow flow meter uses the centrifugal force generated by the circular motion of the fluid when it flows through the elbow sensor, which forms a pressure difference ΔP inside and outside the elbow sensor. The size of the pressure difference ΔP is related to the fluid flow rate and fluid mass (density). ) and the radius of curvature of circular motion. The average flow velocity V of the fluid and the pressure difference ΔP are in a square proportional relationship. Welcome to inquire about the price of elbow flow meter!

Smart elbow flowmeter measures media:

● Liquid: hot water, cold water, light oil, chemical liquid.

● Gas: blast furnace gas, coke oven gas, mixed gas, various single-component and multi-component gases.

● Superheated steam and saturated steam.

● Compressed air.

● Natural gas, liquefied gas, and flare gas.

Features of intelligent elbow flow meter:

● There are no inserts and throttling parts inside the sensor, and there is no pressure loss.

● Suitable for measuring dirty gas and not easy to get clogged.

● The sensor has a wide applicable temperature and pressure range: -50~600℃, 0~30Mpa.

● The requirements for the straight pipe section are low, 5D in front and 2D in back.

● Large-diameter sensors can be modified online using on-site 90° elbows.

● The sensor can work in harsh conditions of high temperature, high pressure, dust, vibration, and humidity.

● Expert algorithm for the full range section, especially for steam measurement. Steam changes with temperature and pressure. Superheated steam often transforms into saturated steam, forming a vapor-liquid two-phase flow medium. In the algorithm, the influence of the vapor-liquid two-phase flow medium on the mass flow measurement is compensated to ensure the measurement accuracy.

● The traffic data of the previous 720 hours, the previous 365 days, the previous 36 months, and the previous 10 years can be queried.

① Elbow sensor (welded or flanged to the pipeline): outputs a differential pressure signal.

② Differential pressure transmitter: Converts the differential pressure signal output by the elbow sensor into a 4-20mA current signal.

③Flow converter: By receiving signals from differential pressure transmitters, temperature and pressure transmitters. Calculate and display flow, temperature, pressure, heat and other parameters.

④Three-valve group: the connection body between the differential pressure transmitter and the pressure tube.

⑤Root valve: Choose a two-way valve (needle valve or ball valve).

⑥Disc condenser: used to cool down the medium when measuring high-temperature medium (steam).

⑦Three-way plug valve: blowdown and backflush.

⑧Pressure pipe: used to connect the differential pressure transmitter and the root valve.

⑨ Pressure transmitter: Used when the pressure of the measured medium (steam, gas) changes greatly.

⑩Temperature transmitter: Used when the temperature of the measured medium (steam, gas) changes greatly. When measuring saturated steam, you can choose either a pressure transmitter or a temperature transmitter to compensate for the flow. When used for heat measurement, 2 temperature transmitters are selected.
