自動温度補正付ウルトラ計数部_容積流量計_02

This register, compatible with all ULTRA OVAL and ULTRA UF-II flowmeter, automatically and continuously measures the process flow with correction to a specific reference temperature (for example, 15 Deg. C.).
All the calculations are carried out digitally to assist the application engineer to build a measurement and control system for oils where a high degree of accuracy is required.
With a single assembly, a pulse and analog output and total flow and instantaneous flowrate on a local LCD display.

FEATURES

1. By inserting a temperature sensor (resistance thermometer) connected to the register into the pipeline, accurate flow measurement is achieved while carrying out flowrate correction (volume conversion) of the process fluid to the reference temperature and temperature correction (3 α ) of the flowmeter body simultaneously
2. The operator can review the total flow and instantaneous flowrate on the local digital display.
3. Complies with the explosionproof construction for maximum safety.
4. In case of power failure and power cycling of an external power source, a built-in nonvolatile memory retains all parameters and the most recent parameters.
