Model: CJDMF-1-CRDescription Insert Tuning Fork Density Meter is a new product which is based on the principle of vibration. Product design using plug-in installation, is widely used in the pipeline, the medium density detection, container open, closed container in the product in the mud slurry, evaporator, solvent separation, oil measurement and other fields. The density of the fluid directly dependents on vibration frequency which tuning fork receives when sensor inserts into media. Sensor’s built-in temperature sensor provides temperature compensation FeaturesPlug in design, plug and play, and continuous online measurementNo moving parts, maintenance free, anti-corrosion design for specific conditionsTemperature compensationCustomize rod lengthThe environment is not sensitive to vibration, and the short rod type is suitable for highpressure pipeline (maximum pressure 20Mpa) Working PrincipleThe sensor is based on the principle of component vibration, and the component part is a part of tuning fork immersed in measured liquid. The tuning fork induces vibration by a piezoelectric device fixed at one end of bottom of the fork. The vibration frequency is detected by two piezoelectric devices fixed at the other end of the fork, and then signal is amplified through the top of the circuit. The liquid density is closely related to the vibration frequency of measured liquid when measured liquid is streaming. When the measured liquid density changes, the vibration frequency of it also changes when the measured liquid is streaming.The density of the measured liquid can be calculated accurately by equation. Technical Parameters Density Range 0.5 – 2.5 g /cc (500 – 2500 kg/m3) Calibration Range 0.8 – 1.2 g /cc (800 – 1200 kg/m3) Accuracy ± 0.002 g /cc (± 2 kg/m3) Repeatability ± 0.0002 g /cc (± 0.2 kg/m3) Temperature Range (Process) -50°C ~ +200°C Pressure Rating 10MPa ~ 20MPa Viscosity Range 0 – 20000 cP Temperature Effect > 0.1 kg/m3/°C (adjusted) Impact from Pressure none Built-in Temperature Sensor PT100 Wetted Parts Stainless steel 316LHastelloy alloy Tine Finish Standard, PFA coated, or Electro-polished Power supply 24VDC,≥50 mA Outputs 4 -20 mA,0-1000Hz,RS485 Modbus RTU Density accuracy - process(20°C) ± 0.1% or ± 0.05% FS of indicated figures Repeatability - process(-40 ~ +85°C) ± 0.05% FS Process connection ANSI 150 ~ 1500 RF DIN 50 PN16 DIN 50 PN40 IDF and RJT hygienic type Defensibility IP65 Outer Covering Aluminum alloy Calculation of fluid measurementV = Q / (1/4 *π*d2)eg: flow rate20m3/h,pipe diameter 100mmV = 20 / 3600 / (1/4 * 3.14 * 0.1 * 0.1)= 0.7m/sec
