Introduces the integration of orifice meter scale installation

Abstract: introduces the integration of orifice meter scale installation matters information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Integration of the orifice meter installation should comply with the automation instrument engineering construction and acceptance specification ( GB50093- 2002). Flow from source components installed in the regulations, i. e. , the measurement of gas flow, taking the upper half of the pressure in the pipeline; During measuring the liquid flow in the pipeline. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a brief introduction the integration of orifice meter scale installation matters article details. Integration of the orifice meter installation should comply with the automation instrument engineering construction and acceptance specification ( GB50093- 2002). Flow from source components installed in the regulations, i. e. , the measurement of gas flow, taking the upper half of the pressure in the pipeline; Measuring the liquid flow rate, lower the line with the horizontal center line of the pipeline into 0 ~ 45 & deg; Within the scope of the included Angle; The upper half of the measurement of steam flow, the pipe with pipe horizontal centerline to 0 ~ 45 & deg; Within the scope of the included Angle; Orifice meter installation notice: 1. The pressure in the upper pipeline gas, Liquid pressure under side but don't in the right, sedimentary grains can be take pressure; The pressure in the tube side steam words, 2. Orifice direction don't wrong, label & other + 'for positive, & other; - 'as a negative, & other; + 'came against the flow direction. 3. Take the positive and negative pressure mouth of guide pipe under any circumstances to keep parallel; 4. Orifice plate is generally going to cooperate with differential pressure transmitter, pressure guide tube connected to the differential pressure transmitter when must pay attention to the negative pressure don't put wrong, & other; H 'is positive, & other; L 'is negative; 5. Measuring gas differential pressure device advice from the top of the pipe, the liquid on the lower part of pipeline, measuring steam if there is one with a condenser, should keep the condenser on the same horizontal height. 6. Straight pipe requirements, in accordance with the requirements of calculation to calculate the installing a orifice plate before and after the straight pipe length, usually for the first 20 d after 10 d to pack ( D refers to the orifice diameter) V cone flowmeter throttle device performance comparing with orifice flowmeter: V cone flowmeter ( Also known as the inner cone cone, V, V cone flowmeter) Measuring instrument is a new generation of differential pressure type flowmeter, tapered tube by a dedicated the throttle device with general differential pressure transmitter, secondary instrument supporting. Tapered tube is skill product, to klunky differential device made a lot of skill improvement, it consists of a circular tube and into the measuring tube and measurement of special core body tube coaxial. Core body and the measuring tube between cylinder is reducing the annular flow, to the throttling of flow of fluid, the throttling process with circular orifice, classical venturi throttling process approximation. Special tapered tube structure, effectively eliminate the now in orifice, the performance of the nozzle, make is not alive during the course of using such as orifice throttling of sharp edges abrasion and accumulate dirt, and can spread before throttling tube fluid velocity gradient and probably forever all kinds of axisymmetric velocity spread additional effective flow channel ( Rectifier) , which can achieve high cutting accuracy of flow measurement with high special riot. Tapered tube flowmeter can be used to various measurement of liquids, gases and steam, is the size of orifice plate and other travel-weary throttling instrument dream and upgrading of products, to improve today's industry, energy metering, supply a valid and reliable measuring wrist. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
