The MRC 7800 Flow Recorder is a microprocessor-based circular chart recorder particularly designed to measure and record flow. It can be used in the foods, beverage, chemical, oil-gas-petro-chemical, and pulp and paper industries, or to measure and record flow for heat exchange and utility output applications. Moreover, its special features make it well suited for water/wastewater flow and totalization applications.

The MRC 7800 Flow Recorder has many special features are what makes it ideal for a variety of applications. Some of these features include: flexible dampening for accurate measurement of erratic or turbulent flow applications, a variety of square root extraction methods, variable exponent to convert head to flow for Parshall flumes and weirs, separate low flow cutoffs for recording and totalization, adjustable flow time base, adjustable decimal position for both flow rate and total, remote reset for totalization, and one button switching between Process Value and Total displays.

Totalization is available on each pen and can be done on a per second, minute, hour, or day basis. Decimal positioning is independent for the process values and totals. The totals can be reset to zero via the keypad or remote contact closure. When totalization is ordered, an optional datalogging feature is available.

Outputs may be assigned for High and/or Low flow. They can also be assigned to activate at preset totalization values for batching applications.

The MRC 7800 Flow Recorder is backed by a three-year warranty and free technical support throughout the life of the product.
