Product catalog summary
Overview of Fork Density Meter:
The Fork Density Meter by Xi'an YunYi Instrument Co., Ltd. is a high-precision vibrating density meter utilizing advanced frequency tracking technology. It is designed for medium density measurement in various containers and pipelines, featuring a built-in temperature sensor for compensation.

Technical Specifications:
  • Measurement Range: 0~3 g/cm³
  • Output: 4-20 mA signal (four wires)
  • Accuracy: 0.3% or 0.001 g/cm³
  • Resolution: 0.0001 g/cm³
  • Installation Modes: DN50, DN80, DN100, and thread installation
  • Temperature Range: -30~120°C
  • Max Working Pressure: 20MPa
  • IP Grade: IP65
  • Materials: Stainless 316, Hastelloy C22, Manganese Alloy 400 with Teflon coating

Installation Guidelines:
Proper installation is crucial for accuracy and stability. The document outlines three classic installation methods: Straight Insertion, Inclined Insertion, and Fixed Mounting Kit. Key conditions include pipe diameter, flow rate, and viscosity limits. Incorrect installation can lead to reduced accuracy and stability.

Electrical Connection:
The meter uses a dual power four-wire connection. It requires a 24V power supply, with output signals of 4-20mA. The display shows both density and temperature.

Operation and Safety Notes:
  • Calibration and error correction can be performed using the digital meter head.
  • Switch between units using the 'E' button.
  • Do not expose the instrument to corrosive liquids or pressures beyond specified limits.
  • The instrument is suitable for explosion-proof environments and can withstand 1.2 times the maximum testing pressure.
