Tri-clamp Electromagnetic Flow Meter – Overview

The Tri-clamp Electromagnetic Flow Meter is a kind of volume flow meter. It is quick and easy to install. It is made of stainless steel, which can easily be disassembled and cleaned.  This prevents pollution during use, and the accumulation of measuring fluid residues in the measuring tube.  It is based on Faraday’s law of electromagnetic induction which is used to measure conductance greater than 20 μS/cm volume of conductive liquid flow. This measures the general volume of conductive liquid flow, but can also be used to measure strong acids, alkalis, strong corrosive liquids, mud, pulp, etc. The long-life Harmelss Food Grade Stainless Steel allows it to come into contact with food directly. It can withstand high temperature disinfection, making it ideal for use in dairy.  It has current output and pulse output for connecting with PLC or other devices and is RS485/HART/Profibus compatible.

The Tri-clamp Electromagnetic Flow Meter is suitable for use in drinking water, milk, groundwater, beer, wine, jam, juice and other food & drink industries. It is also widely used in paper pulp and gypsum slurry because it can be cleaned easily.

Table 2: Tri-clamp Electromagnetic Flow Meter Electrode Material Selection

Electrode material Applications
SUS316L Applicable in water, sewage and low corrosive mediums.
Widely used in industries of petrol, chemistry, carbamide,etc
Hastelloy B Having strong resistance to hydrochloric acid of any consistance which is below boiling point.
Resistable against vitriol, phosphate, hydrofluoricacid, organic acid etc which are oxidable acid, alkali and non-oxidable salt.
Hastelloy C 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 reduces corrosion.
Tantalum Having strong resistance to corrosive mediums that is similar with glass.
Applicable to most chemical mediums.
Except for hydrofluoric acid, oleum and alkali.
Platinum-iridium Applicable to most chemical mediums except for ammonium salt.
