Product Overview
The TBQSe quantometer is a based on the principle turbine flowmeter with an integrated electronic index head. The TBQSe is designed for flow and volume measurement for natural gas, nitrogen, air (and other gases on request) in non-custody transfer and process applications. It is designed and approved according to the European guidelines of 2014/68/EU and 2014/34/EU, and will be certified as an intrinsically safe device according to ATEX and IECEx Ex-Zone1; Ex II 1G Ex ia IIC T4. The electronics are installed in an explosion proof enclosure. It is suitable to be installed in hazardous area of Catagory 2 (ATEX / IECEx Ex-Zone 1) II 2G Ex ia IIC T4 Ga.
Features
■ Compact structure
■ Independent catridge design with good interchangeability and convenient maintenance. 180° rotation allowed for meter head for easy installation.
■ Low power consumption technologies adopted for continuous long-term running with only the internal battery.
■ Segment LCD display adopted for clear display and easy reading of periodically switching standard flow, total amount, pressure and temperature.
■ 4 built-in buttons and electrical index head for related parameter settings; RS485 or MBUS communication interfaces are also available for parameter ssettings using the equipped upper computer software.
■ 2 digital output interfaces HF and LF available for high-frequency signal output of instantaneous flow rate at measyrement conditions and low-frequency output of total amount at reference conditions.
■ RS485 or MBUS available for serial communication interfaces, and MODBUS RTU and TANCY1.3 protocals supported or can be customized upon requirement.
■ Two-wire 4-20 mA standard current signal output available for easy connection with systems including DCS and secondary instruments.
■ EEPROM data storage technologies adopted with comprehensive history runing data records for user query.
■ Store latest 1500 records for total amount, flow, pressure, and temperature at reference and measurement conditions with time stamp.
■ Password protection preventing unauthorized changes to parameters.
■ Anti-hazard rating: Ex d IIB T4 Gb or Ex ia IIC T4 Ga; Ingress protection: IP65
■ Ambient temperature: -25°C ~ +55°C (determineed by the corrector during configuration)
■ Medium temperature: -20°C ~ +80°C
