Quick Answer The LC-B and LC-C stainless steel oval gear flow meters are positive displacement meters built in 304 (LC-B) or 316 (LC-C) stainless steel for acid, alkali, and other corrosive liquids that would attack a cast iron housing. Sizes run DN10 to DN200 (3/8 inch to 8 inch), accuracy is 0.5% or 0.2%, and the meter handles viscosity up to 2000 mPa·s without needing a straight pipe run. Nominal pressure is 2.5 MPa (362 psi) up to DN50 and 1.6 MPa (232 psi) from DN80 up. Silver Automation Instruments ships it with mechanical or digital registers, in pulse, 4-20 mA, or HART output. |
An oval gear flow meter is a positive displacement meter. A pair of oval gears rotate inside a measuring chamber, and each rotation pushes a fixed volume of liquid from inlet to outlet. The revolution count and rate convert directly into totalized and instantaneous flow, so the meter does not need a long straight pipe run before or after it the way a vortex or electromagnetic meter does.
Cast iron housings, model LC-A, cover general oil and non-corrosive fluid duty. Once the liquid turns corrosive, acid, alkali, brine, or an organic solvent, cast iron corrodes and the internal clearances open up, so accuracy drifts fast. That is the gap the stainless steel LC-B and LC-C models fill.
LC-B uses 304 stainless steel for the shell, cover, and oval gears. It handles mild to moderately corrosive fluids, dilute acids, alkaline solutions, and general chemical processing lines, at a lower cost than 316.
LC-C steps up to 316 stainless steel, which holds up better against chlorides and stronger acids, the kind of duty you see in concentrated acid dosing, salty process water, or coastal chemical plants. If your fluid carries chlorides at any real concentration, or you are simply not sure, 316 is the safer default. Send us the fluid name and concentration and we will confirm which housing material fits before you order.

Chemical dosing skids, acid and alkali storage transfer, and wastewater treatment lines make up most of the demand we see for the LC-B and LC-C. Southeast Asian palm oil and specialty chemical plants run them on caustic and organic acid lines. Middle East fertilizer and desalination plants lean on the 316 version for chloride-heavy streams. In South America and Africa, mining reagent dosing, sulfuric acid and cyanide solution lines among them, is one of the more common applications, usually paired with a digital register and 4-20 mA output for SCADA integration.
What is the difference between the LC-B and LC-C stainless steel oval gear meters?
LC-B is built in 304 stainless steel, for general corrosive service. LC-C is built in 316 stainless steel, for stronger acids and chloride-heavy fluids. Housing, cover, and gears are stainless in both, only the grade changes.
What is the maximum viscosity this meter can handle?
Up to 2000 mPa·s. Above that threshold it counts as a high viscosity flow meter medium and needs separate confirmation from our engineering team on flow range and drive torque.
Does the meter need a straight pipe run before and after installation?
No. As a positive displacement meter it reads flow through direct gear rotation, so it does not need the upstream and downstream straight runs that vortex or electromagnetic meters need.
What output signals are available?
A mechanical register with pulse output, or a digital register with 4-20 mA, pulse, or HART output, both available in an explosion proof housing rated ExdIICT6.
