Flow Measuring Electro Irrigation Water Electromagnetic Liquid Flowmeter

Product Description

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

1. There's no influence to accuracy with change of fluid density, viscosity, temperature, pressure and conductivity.
2. Do not require much upstream and downstream straight run can be installed in relatively short meters.
3. High definition LCD display with backlight and it's easy to read.
4. Adopted PFA lining for high-pressure electromagnetic flow meter with high pressure, negative-pressure resistance,  widely used in petrochemical, mineral industry.
5. Generally used for process detection, and measurement for ore pulp, paper pulp and paste liquid.
6. 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.
7. Ex-type instrument is used for relative Ex-proof environment.

Product Parameters

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	Excellent elasticity, high breaking force and good wear resistance Corrosion resistance to general low-concentration acid, alkali and salt medium, not corrosion resistance to oxidizing medium	Water, sewage Weak-abrasive mud, ore slurry
Polyurethane rubber	Excellent wear resistance (equivalent to 10 times that of natural rubber) Poor acid and alkali resistance Can not be used in water mixed with organic solvents	Neutral strong abrasive slurry, coal slurry, mud, etc.
Fluorosilicone rubber	Excellent elasticity, high breaking strength, high temperature resistance	Water temperature: ≤160ºC
PTFE	The material with the most stable chemical properties in plastics can withstand boiling hydrochloric acid, sulfuric acid and aqua regia, as well as concentrated alkali and various organic solvents, but it is not resistant to corrosion by chlorine difluoride, high-flow liquid fluorine, liquid gas, and odor. Poor wear resistance	Concentrated acid, alkali and other strong corrosive medium
F46	Corrosive ability equals to PTFE Capable of low wear Strong negative pressure resistance	Equals to PTFE Can be used for low abrasive medium
PFA	Corrosive ability equals to PTFE Strong negative pressure resistance	Applicable for negative pressure environment

FAQ

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.
