A:The product says all:
The LZ series metals tube floats the son flowmeter to adopt a variable area type to measure principle, can fly to to the variety of the air and liquid carry on diagraph.This series the flowmeter specification the species safety, have the designation type,give or get an electric shock a Far EasTone Telecommunications Co., Ltd type,bear a type,clip a set of type,flameproof type products with various etc., give or get an electric shock the Far EasTone Telecommunications Co., Ltd type have 0-10 mAs and 4-20 mAs of standard emulation the quantity signal output, can and DDZ-Ⅱ or DDZ-Ⅲ the dynamoelectric unit combine the gauge kit an usage, having the spot an accumulation,numerical communication in the meantime,the spot modification diagraph parameter,different power supply method etc. function, and can make other method 蘭 sizes exclusively for the customer,higher work pressure and take a special specification species of the filter,extensively applied petroleum,chemical engineering,generate electricity,food,make realms, such as medicine and the water processing...etc..
The LZ series metals tube floated flowmeter is mainly constitute by two parts:1 spread a feeling machine;2 conversion machines.The that spreads the feeling machine to become all of the conversion of the discharges to float son moves quantity, matching system through the , will float the son to move the size that the quantity passes the conversion machine to indicate a discharge, the conversion machine has the M1 and M2 two kinds of structure forms, going together with to pack to change to send to a machine to constitute different function to combine differently.

Clip a set of conjunction method standard is:GB/T9119 PN1.6 DN15
Eight,install
The flowmeter should hang gearing, the flowmeter center line and lead line clip Cape not more than 5 °s, promising in the upper stream beard of the flowmeter 500% Mr.s call an entrance of path keeps the tube segment, the downstream promises the 250 mm export keeps a tube a segment.If lie to imply miscellaneous quality of solid in the quality, should add a filter in the flowmeter upper stream;If lie to imply the iron magnetism material in the quality, should install filter in the upper stream of the flowmeter.For the sake of easy to maintenance with clean and don't influence production, the suggestion install side tube road.
In order not to because the piping cause of the flowmeter transform, install the method have to and gauge together stalk and parallel mutually, and prop up piping properly with the stalk that avoids the piping vibration and lets up flowmeter toward burden, measure system and should install in the downstream of the flowmeter in the control valve.
Should promise the piping pressure not less than 500% flowmeters pressures to lose to float by make a sub- stability work while useding for measuring air.
Nine,enclosure
Can provide to keep the tube segment and form couples enclosures, such as method ,filter and the air damping device...etc. in front and back for the customer.
If lie to imply the iron magnetism grain in the quality, should install a filter entrance in the flowmeter.Stick it had to arrange in spiral way in the filter with let up the pressure loss with maximum limit, each stick is all gather by PTFE four the fluorine B sparse package, prevent°from lying the corrosion of the quality.
The structure of the filter sees diagram:

The temperature influence:0.5%/10 ℃s
Power supply electric voltage:13-30 V DC
Power supply depletion:≤ 250 mWs
Load resistance:See diagram
11,the limit the switch report to the police device
Only for a switch equip at the part in the indicator from respond head,the aluminum slice...etc. to constitute, respond a head is install the position that is point the aluminum slice of the needle stalk to incise in the ability, the position that passes a change to respond a head can set the limit a value arbitrarily.Respond a head the exportation signal turn the sub- discharge designation control instrument for metals.
Technique parameter
1.Power supply power supply:The 220 V AC ± 10%
2.The consume:≤ 3 Ws
3.The work temperature:-25 ℃～s 60 ℃s
4.The exportation touches some capacity:220VAC 3A
Connect line diagram
The change beard that reports to the police to order openned to cover ago, loosenning bolt of open the little finger needle of engrave one degree dish, adjusting to the back of the position of[with] demand, was tightly solid the bolt again, packing to like to cover ago finally.
12,the flameproof product usage regulation
The metals tube floats the son flowmeter, meeting the request of the GB3836.1 and the GB3836.4 standard provision through the national class instrument gauge flameproof safe direct examination station(NEPSI) examination, product the flameproof marking is the CT5 of ib Ⅱ , the flameproof qualified certificate number is a GYB01319.The customer should notice a following item while use product:
1.The metals tube floats the son flowmeter outer shell to establish to connect ground to carry son, customer while use should the credibility connect ground
2.The metals tube's floating the biggest usage environment the temperature scope of the son flowmeter is-20 ℃～s+55 ℃s.
3.The metals tube's floating the son flowmeter have to and LB906 together the 納 safe grid kit usage constitute flameproof system of this Anne.The system connects line to is shown as diagram:
4.The cloth line of this Anne's system should avoid the influence of the outside electromagnetism interference as far as possible, and distribute electric cable the parameter control at the 0.008 uFs and the 2 mHs in.
5.The safe grid has to be install in the safe place.The gearing,usage of the safe grid and maintenance should obey the safe grid usage manual.
6.Control gauge connected with each other with safe grid of tallest work the electric voltage or its electric circuit the internal possibility produce of the tallest electric voltage can not be high in the 250 VRMSs.
7.Customer at install,the usage and maintenance give or get an electric shock the Far EasTone Telecommunications Co., Ltd series metals tube to float the son flowmeter, must read the product usage manual hard, and obey strictly in the meantime 《the People's Republic of China explode a safe rules distance(try a line) of dangerous place electricity 》. |
