The main features of the universal WB-2100 quantitative controller (hereinafter referred to as the controller) are:

Suitable for flow display, accumulation, and control functions of various liquid media;

Input multiple flow sensor signals (such as vortex, turbine, electromagnetic, Roots, elliptical gear, dual rotor, orifice plate, etc.)VVarious flow meters such as cone, Annubar, mass flow, etc;

Flow input channel: capable of receiving frequency signals and various analog current signals;

Temperature input channel: capable of receiving various analog current signals;

Can provide transmitters+24V DC，+12V DCPower supply with short-circuit protection function, simplifying the system and saving investment;

Fault tolerance function: Temperature/When the density compensation measurement signal is abnormal, use the corresponding manually set value for compensation calculation;

Traffic resend function, output current signal of traffic, update cycle1Second, meet the requirements of automatic control;

The instrument clock and timed automatic meter reading function, as well as printing function, provide convenience for metering management;

Rich self checking and self diagnostic functions make the instrument easier to use and maintain;

The three-level password setting can prevent unauthorized personnel from changing the set data;

There are no adjustable devices such as potentiometers or coded switches inside the instrument, thereby improving its shock resistance, stability, and reliability;

Communication function: It can communicate with the upper computer through various communication methods to form an energy metering network system RS-485； RS-232； GPRSTheCDMA， Broadband network.
