Maxiflex MP Meter Prover Module Model M1714B Meter Prover Module. DATASHEET FEATURES • Performs pulse interpolation for proving oil & gas flow meters in accordance with the Manual of Petroleum Measurement Standards Accepts up to four detector switch inputs from a meter prover. Receives pulses from a flow meter to be proved. Performs pulse interpolation calculations in real time. Compatible with the Maxiflex M1713A four channel pulse integrity module to support multiple flow meters on a single meter prover. Fits in any MAXIFLEX base I/O slot The Manual of Petroleum Measurement Standards Chapter 4 (Proving Systems) Section 6 (Pulse Interpolation) defines a method of “double-chronometry” or pulse interpolation for increasing the resolution of flow metering pulses when proving gas or oil meters used in custody transfer applications. General purpose electronic control equipment (such as PLC’s) are generally not able to meet the fast counting requirements needed to implement this method. This Maxiflex M1714B MP (Meter Prover) module is specifically designed to interface with compact meter provers, and provide the complete meter proving logic and pulse interpolation calculations in accordance with the standard. This module performs the following functions: • • Accepts up to four detector switch inputs from a meter prover. Any two can be enabled for a meter prover “run”. Accepts a pulse input from the flow meter to be “proved”. This input is designed to be compatible with the Maxiflex 4PI (four channel pulse integrity) module pulse output so that any of the flow meter pulse streams into any Maxiflex 4PI module in the system can be software selected for this function. Upon software command, performs the pulse interpolation function (as defined in the Manual of Petroleum Measurement Standards) and provides the result to the Maxiflex CPU Module. SPECIFICATIONS pulse interpolation using the “double chronometry” method in accordance with the Manual of Petroleum Measurement Standards Chapter 4 (Proving Systems) Section 6 Detector Switch Inputs Number 4 detector switch inputs Opto coupled input (externally powered) Electrical Specifications Input “ON” voltage Field Termination Screw clamp Plug-in Terminal Blocks Screw Terminal Wire Size Three LED indicators per switch input: Green indicates switch is “ON” Yellow indicates switch is active Red indicates switch has activated.
