Turbine flow measurement for Slurry flow meter, dirty water, 2" - 48"
Product Description
The electromagnetic flow meter includes both 4-20mA and pulse output. The transmitter can be mounted either integrally to the flow sensor or remotely. The transmitter features a three-line LCD that displays the flow total, flow velocity, flow rate percent of range, and alarm settings. A four-button keypad is used to change settings. There are 27 flow unit options to choose from programmed into the transmitter.
This magmeter is available in sizes from 1 to 24 inches (other sizes are available upon request). The magnetic flowmeter has no parts to obstruct flow resulting in no pressure loss and the 0.25% accuracy is not affected by temperature, pressure, viscosity, density or flow profile. With no moving parts, practically no maintenance is required. The chloroprene rubber sensor liner is suitable for liquid temperatures from -13 to 176°F and is compatible with most water-based fluids and many chemicals.

Work theory
This technology of magnetic electromagnetic flowmeter has a number of advantages when it comes to liquid flow measurement. The sensors are generally inserted in line into the pipes' diameter, and are therefore designed such that they do not disturb or restrict the flow of the medium under measurement. As the sensors are not directly immersed in the liquid-there are no moving parts-there are no wear and tear concerns.
The method of magnetic electromagnetic flowmeter measures the volume flow, which means the measurement is insensitive to changes in effects such as fluid density, temperature, pressure, and viscosity. Once the electromagnetic water flow sensor measurement transmitter meters is calibrated with water, it can be used to measure the other types of conductive fluid-with no additional correction. This is a significant advantage that other types of flow meters don't have.

| Main performances of the electrode materials | |
| Electrode material | Applications |
| Stainless steel SS316 | Applicable in water, sewage and corrosive mediums. 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. Also resistible 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 | Applicable in 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 | Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemical mediums. Except for hydrofluoric acid, oleum and alkali. |
| Platinum-iridium | Almost be applicable in all chemical mediums except for aqua fortis, ammonium salt. |
