First, the insertion electromagnetic flowmeter features plug-in addition to the general characteristics of electromagnetic flowmeter electromagnetic flowmeter, but also has its own unique advantages: 1, simple structure, no moving parts, .2 long life, small size, light weight, easy to install, less maintenance. 3, there is cut-off valve insertion electromagnetic flowmeters can be installed to achieve a continuous flow, disassemble, user maintenance, repair. 4, is not affected by the tested pipe material under test. 5 , no lining, no grounding ring two, insertion electromagnetic flowmeter technology parameters 1, the nominal pipe diameter and flow range in Table 12, the measured fluid conductivity:.> 5 μ s / cm 3, nominal pressure: 0.6MPa 1.0MPa 1.6MPa 4, the measured medium temperature: the angle between 0 ~ 60 ℃ 5, sensor positioning rod axis with the pipe axis tolerance + 5 °, the insertion depth tolerance 3mm 6, length of straight pipe requirements: upstream sensor straight pipe length ≥ 20D; sensor downstream straight pipe length ≥ 7D 7, converter main technical performance indicators: a, output signal: DC current: 4 ~ 20mA (allow negative cut resistance is 0 ~ 500 Ω, optical isolation) b, power supply : The maximum length of the connecting cable between AC or 24V Dc c, sensors and Xuan converter for 100m d, the working environment: temperature 0 ~ 40 ℃; relative humidity less than 85%; ambient air should not contain corrosive gases e, Display instantaneous flow rate and total flow 8, Accuracy: When the nominal pipe diameter DN ≤ 150, in order to ± 1.5% R when the pipe nominal diameter DN ≥ 200, in order to ± 1.5% R ± 2.5% R 9, enclosure protection rating : IP67 Third, the selection of parameters and model tag for insertion electromagnetic flowmeter design unit should be based on the main technical indicators of the product, with reference to the actual situation of the user's selection of a suitable flow range to determine if the user is ready pipeline. can. If you do not do the pipeline, we must first determine in accordance with the applicable table selection phase flow and flow range of the sensor according to the sensor caliber caliber, then consider installing a shut-off valve type there no shut-off valve type of sensor is installed. 2, the probe and insert the rod in the form of the probe is determined according to the form of suspended solids in the media, the general suspension of elections more difficult to frequent disassembly open, otherwise the selected type catheter insertion rod form of installation. General screw relatively easy to install. 3, pressure and use the user can select the sensor according to the requirements of the pipeline pressure pressure indicators for general insertion electromagnetic pipeline pressure smaller occasions, for medium to large pipe recycled water, the source of water and water metering. In addition, the insertion integrated electromagnetic flowmeter with the same caliber, split electromagnetic flowmeter cheaper price compared to four sensor selection table insertion electromagnetic flow sensor installation - (cut-off valve; 1- No shutoff valve). Probe form - - (A open type, B-type catheter) is inserted into the rod form - (a screw, two light rod) five, insertion electromagnetic flowmeter selection table environment - (B: Explosion; no: Non-Explosion) converter model - (6 A: integration; 5 A: sub-type) structure - (Y: one size: sub-body) installation - (cut-off valve; 1 - no shut-off valve) probe in the form of - (A open style; B ducted) Plug-in rod form - (a screw; 2 light rod)
