Introduction

The tuning fork density meter is an online process instrument that measures liquid or slurry density by detecting the resonant frequency change of a vibrating fork. It provides real-time, continuous density and concentration output with high accuracy (±0.001 g/cm³) and excellent stability. The device has no moving parts, requires little maintenance, and supports 4-20 mA plus RS485 Modbus communication. It is available in insertion, flange, or sanitary clamp designs, with 316L stainless steel wetted parts.

Typical Applications

• Chemical & Petrochemical – Acid/alkali concentration, polymer monitoring

• Oil & Gas – Crude oil density, fuel blending, interface detection

• Food & Beverage – Brix measurement in juice, beer, milk, syrup

• Pharmaceutical – Solvent concentration, fermentation control

• Mining & Mineral Processing – Slurry density, ore pulp, tailings

• Water & Wastewater Treatment – Sludge density, polymer dosing control

• Marine & Shipbuilding – Fuel viscosity/density, ballast water monitoring
