Plug-in electromagnetic flowmeter
One. Product overview
Plug-in electromagnetic flowmeter is a kind of measuring induction of conductive fluid volume flow meter.LDE insert type electromagnetic flowmeter is in the pipeline on the basis of electromagnetic flowmeter developed a kind of new type of fluid flow meter.It on the basis of retain the advantages of pipeline electromagnetic flowmeter, electromagnetic flowmeter for pipeline to install on a great difficulty, large fees, according to the principle of magnetic (NIKURADS), Mr Khoja, by measuring the average flow velocity of the fluid with electromagnetic method, to obtain the volume of fluid flow.Especially the hole under pressure to bring the pressure after the installation, insert type electromagnetic flowmeter in the case of without a stop (water) installation, can also be used in cast iron pipe, cement pipe, PE pipe installation.Plug in the successful development of electromagnetic flowmeter for detection provides a new means of fluid flow.
2. Features:
, plug-in electromagnetic flowmeter in the pipeline flow tests, with the installation of absolute advantage and price advantage.
Converter adopts optimized design, tight structure, easy to electrical installation, converter and sensors are interchangeable, are free to change the measuring range (0.5 m/s ~ 10 m/s).
Instrumentation "automatic zero" principle, to eliminate electrochemical interference signal, zero stability.
Converter and sensor has many kinds of protection grade and the installation method, is suitable for diving installation IP68 level.
, suitable for water, sewage, acid, alkali and other electrical conductivity in 5 mu s/cm above the liquid flow detection, especially suitable for water supply and drainage pipeline flow measurement.
Only related to insert depth, flow measurement, therefore the meter wide commonality, strong interchangeability, a model can be applicable to a variety of specifications of the pipe flow measurement requirements.

Example: select a plug-in electromagnetic flowmeter measurement sewage local display type, the user pipe (, rubber lining, stainless steel electrode, 4 ~ 20 ma output, no communication, maximum flow rate of 30 m3 / h.Model should be: LDE - M1X100-30-50 s
2. The choice of electrode material
Should be according to the current body of corrosive to select electrode material, please check the manual, for special fluid corrosion test should be done
material | Code name | Corrosion resistance of |
316L | V | 1 is suitable for industrial and domestic water, raw water well water, urban sewage and other neutral solution |
Hartz alloy C | HC | 1 is suitable for the oxidation resistance of acid, such as nitric acid, mixed acid and chromic acid and sulfuric acid mixture |
Hartz alloy B | HB | 1 for the oxidation of acid, alkali, salt, such as sulfuric acid, phosphoric acid, hydrofluoric acid have good corrosion resistance |
titanium | Ti | Seawater, all kinds of chloride hypochlorite suddenly and a variety of hydroxide of corrosion |
tantalum | Ta | Except hydrofluoric acid, can almost everything the corrosion of chemical medium.But the price is expensive |
platinum | Pt | For all of the acid and alkali salt solution (fuming sulfuric acid and nitric acid) |
Tungsten carbide | W | Excellent wear resistance, dedicated to the mud medium, such as pulp up to wear and tear |
3. The selection of lining materials
Should be according to the measured medium corrosive wear and tear "to choose lining material and temperature
The lining material | Corrosion resistance of | Working temperature | Scope of application | ||
Neoprene Ne | Generally low concentration of acid and alkali salt corrosion resistance | - 20 ~ 70 ℃ | Industrial wastewater of low concentration acid and alkali salt with water | ||
Polyurethane rubber PO | Has excellent wear resistance, strong dedicated to wear and tear "slurry, no corrosion | - 10 ~ 60 ℃ | The liquid containing solid particles (cement slurry, etc.) | ||
FEP FEP | 1 heat corrosion resistance and PTFE | - 40 ~ 180 ℃ | In addition to the strong abrasiveness medium such as mortar all fluid.As with PTFE, can be used for beverages with health requirements of the medium | ||
Teflon PTFE | Almost all can resist corrosion of chemical substances, poor wear resistance | - 40 ~ 180 ℃ | Cannot be used for negative pressure pipeline and wear and tear "strong fluid |
