Flow Measuring Electro Irrigation Water Electromagnetic Liquid Flowmeter
Overview
The smart flowmeter is a kind of high-accuracy and high-reliability flow meter to measure flow volume of conductive liquid or serum in a closed sealing pipeline. Widely used in electric power plant, oil and gas industry, chemical industry, coal, metallurgy, mining, paper making, water supply and drainage, food and other industries.Features
Features
- There's no influence to accuracy with change of fluid density, viscosity, temperature, pressure and conductivity.
- Do not require much upstream and downstream straight run can be installed in relatively short meters.
- High definition LCD display with backlight and it's easy to read.
- Adopted PFA lining for high-pressure electromagnetic flow meter with high pressure, negative-pressure resistance, widely used in petrochemical, mineral industry.
- Generally used for process detection, and measurement for ore pulp, paper pulp and paste liquid.
- There's three inner calculators- positive gross, reverse gross and difference value to dual measuring system to display positive, reverse flow with varied kinds of output: current, pulse, digital communication and Hart.
- Ex-type instrument is used for relative Ex-proof environment.
Electrode selection parameters
| Electrode Material | Application |
| SUS316 | Applicable for water, sewage and low corrosive medium; Widely used in industries of petrol, chemistry, carbamide etc. |
| Hastelloy B(HB) | Having strong resistance to hydrochloric acid of any consistence which is below boiling point. Resistable against vitriol,phosphate, hydrofluoricacid, organic acid etc which are oxidable acid, alkali and non-oxidable salt. |
| Hastelloy C(HC) | Be resistant to oxidable acid such as nitric acid, mixed acid as well as oxidable salt such as Fe+++,Cu++ and sea water |
| Titanium(Ti) | Applicable for seawater, and kinds of chloride, hypochlorite salt, oxidable acid (including fuming nitric acid), organic acid, alkali etc. Not resistant to a pure reducing acid (such as sulphuric acid, hydrochloric acid) corrosion. But if acid contains antioxidant (such as Fe+++,Cu++) is greatly reduce corrosion |
| Tantalum(Ta) | Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemicals mediums except for oleum and alkali |
| Platinum-iridium | Almost be applicable in all chemical mediums except fortis, ammonium salt |
| Stainless Steel Coated Tungsten Carbide | Applicable for non-corrosive and strong abrasive liquid |
Lining material selection parameters
| Lining material | Function | Application |
Neoprene |
| Water, sewage Weak-abrasive mud, ore slurry |
Polyurethane rubber |
| Neutral strong abrasive slurry, coal slurry, mud, etc. |
| Fluorosilicone rubber | Excellent elasticity, high breaking strength, high temperature resistance | Water temperature: ≤160ºC |
PTFE |
| Concentrated acid, alkali and other strong corrosive medium |
| F46 |
|
|
| PFA |
| Applicable for negative pressure environment |

Q: The new magnetic flap liquid level gauge can't show liquid level?
A: 1.check whether there is block in by pass pipe 2.check the the density of medium 3.check whether the float ball is stucked by float ball.
Q: The longest length of magnetic flap liquide level gauge?
A: the length is customized,but in order to be convenient for transport,if the length is over 6m,we recommend
Q: If the float ball is installed at the wrong opposite direction,what's the influence?
A: reading level will be higher than true level,usually higher by length of floatball-70mm
Q: What's installation details of magnetic flap liquid level gauge ?
A: 1.before installation,check specification with label plate. 2.There shouldn't magnetic field within 400m
Q: There is problem in output signal 4--20mA?
A: 1.Check working power supply 2.check wiring 3,check load resistance 4.verify measuring range,zero point
Q: what's specification we need to know before purchasing magnetic flap liquid level gauge?
A: medium density,working temperature,working pressure,material,flange center to center distance,flange standard,whether need 4--20mA output signal;whether need level alarm.
