Introduction: TQ-813 tuning fork online viscometer is an online viscometer developed by our company for marine heating oil supply system and large mechanical lubrication system. The product is also suitable for low viscosity materials. In marine and power applications, the TQ-813 tuning fork online viscometer is a major innovation in the measurement and control of heavy fuel oil (HFO) for engines, turbines and burners. With a multivariable design, the TQ-813 online viscometer accurately measures viscosity, density and temperature in real time, enabling true kinematic viscosity analysis. The instrument integrates the above parameters to form a complete transmitter with two analog outputs as standard. Features: 1. No moving parts – minimal maintenance 2. Continuous measurement of viscosity, density and temperature 3. Reference viscosity and density measurement 4. User configurable 4-20 mA output 5. All parameters can be output via MODBUS 6. Sensor with PFA coating to resist product/asphalt adhesion 7. Adapter is suitable for marine viscometer using prior art 8. Accurate online measurement with reference to viscosity and density 9. More reliable: no moving parts or seals 10. Can be inserted directly into the pipe or capillary viscometer installation 11. Stronger ability to resist clogging and anti-impurity Technical Parameters: Viscosity accuracy: ±0.2cSt (0.5-10cSt)±1 cSt (10-100cSt) Viscosity range: 0 – 100cSt0 – 500cP Repeatability: ±0.50% reading Density accuracy: ±0.001 g/cc (±1kg/m3) (±0.06lb/ft3) Repeatability: ±0.0001g/cc (±0.1kg/m3) (±0.006 lb/ft3) Pressure effects: neglected Temperature range: -50 to +200oC Wetted parts: 316L stainless steel, PFA Electronic components: One-piece transmitter with 2 x 4-20 mA, RS485 Modbus
