Mass flow indicators controllers gas flow model 845g ( microprocessor based electronics ) introduction pantech instruments model 845g represents flow indicators totalizers controllers for mass flow applications related to standard gases flow. The instrument is so designed to accept 3 inputs of flow, pressure and temperature at a time. Based on these inputs, and high end algorithms of standard gas equations fed in the chip, the instrument calculates mass instantaneous flow rate to a resolution of 44.5 digits. Totalized value is displayed through 8 digits red led and this totalizer value is always protected against power failures through internal memory structures of microprocessor. Optionally the instrument is designed to give two contact relay outputs and a retransmission isolated signal on instantaneous flow rate. Serial communication outputs for computer system interfaces are also given optionally. All configurations, calibrations and output fine tunings etc. Can be performed by front four keys only without opening the instrument. In the core of all the functions lies the latest and highly proven microprocessor based chipsets. The high end softwares ensure the most user friendly interactions by the user. The instrument incorporates low drift operational amplifiers and industrial grade components for long trouble free operation. Burn in of each module ensures long trouble free operations. model 845g at a glance : used for the mass flow calculation of gases that follow standard gas equation. accepts three inputs flow ( ma ), pressure ( ma ), temp ( ma rtd pt.100 thcpl ). gives efficient pressure and temp. Compensations for mass flow calculations. refers hi end algorithms of standard gas equations. the user is allowed to feed in maximum pressure transmitter range in kgcm2, operating pressure in kgcm2, operating temp. In deg. C, flow rate.
