Funnel viscometer is a simple device used for testing drilling fluid’s relative viscosity (compared with water). The time of drilling fluid flowing out from funnel under gravity can show us the viscosity of fluid. Its standard value : time for flowing out 500ml standard distilled water is 15±5S in 20±2℃. ZLN-1A funnel viscometer is composed of funnel made of metal materials funnel, strainer, measuring cylinder and a plastic measuring glass, which is widely used in petrol and geological survey, especially in field drilling.
