Flowmeters are Viscosity-Insensitive

Universal Flow Monitors says its L Series viscosity-insensitive flowmeters assure delivery of circulating lubrication oil to machinery bearings in high-vibration applications such as mining, ore processing and rock crushing. These piston-style flowmeters maintain +/- 5% accuracy for lubrication oils with a viscosity range between 40 and 200 centipoise. Although operating in the 40–200 CP viscosity range is standard, a meter can be optimized for specific viscosities within that range. The viscosityinsensitive L Series meters can monitor lube oil flow rates from 2 to 20 gallons per minute (7.6 to 75.7 liters per minute). The meters monitor rate of oil flow, provide flow rate indication to assist in problem diagnosis, and respond immediately if flow goes too low. L Series meters are available with a field-adjustable, high-vibration Single Pole Double Throw (SPDT) Micro Switch to trigger equipment shutdown in high-vibration applications and protect against bearing damage. The L Series units are mechanical and require no power. They are Type 4 weatherproof units with wetted parts of aluminum, brass, stainless steel and Viton fluorocarbon elastomer. The meters accommodate maximum ambient temperatures of 150°F (65°C), maximum fluid temperatures of 200°F (93°C) and maximum pressure to 500 psi (35 bar).
