HGMT101-DCB multivariable transmitter is generally used together with Annubar, Delta, Verabar, balance, V-cone, orifice, nozzle and Venturi flow sensor. Battery-powered type available for site display, no need of external power supply; design of all-isolation output and ultra-strong anti-interference shields all distractions; can output pulse, current (4-20mA) and RS485 (need external power supply); with built-in temperature and pressure sensor, and automatic temperature and pressure compensation for gas and steam; turndown 1: 100, 1: 200, 1: 400, accuracy 0.5%, 0.2%, 0.1%, 0.05% optional, display of temperature, pressure, working flow and standard flow for gas; display of temperature, pressure, density and mass flow for steam.
Built-in flow totalizer can display instantaneous flow and cumulative flow at the same time, and provide the following output: A 3-wire pulse remote output (standard configuration); B 2-wire / 3-wire current output (optional); C RS485 Output (optional).
I Function of HGMT101-DCB multivariable transmitter
HGMT101-DCB multivariable differential pressure flow transmitter is with built-in flow totalizer, uses micro-power microcontroller (power <= 300uA); industrial lithium battery 3.6V DC for working of 2-3 years.
Built-in flow totalizer uses large-screen LCD display, display of 6-bit instantaneous flow, accurate to 2 bits after decimal point (0 ~ 9999.99m3 / h) or 1 bit (0 ~ 99999.9m3 / h); display of 9-bit cumulative flow, accurate to 4 bits after decimal point (0 ~ 99999.9999m3) or 5 bits (0 ~ 9999.99999m3).
