Gas Meter Volume Pulsers
MicroPulser™ is a precision microprocessor based dual channel flow rate transmitter designed to be installed between the meter and vertical index, or instrument on most industrial/commercial gas flow meters. MicroPulser provides high resolution flow rate information to RTU's, flow computers or any other device requiring accurate flow rate information. Flow volumes can be calculated more frequently using MicroPulser due to the 1000 pulses per revolution output. In some cases such as sampling systems or flow rate telemetry, quick updates can significantly improve overall performance and accuracy. High speed flow computers with fast sample rates can be significantly improved with the MicroPulser's high resolution.
A primary cause of pulser failure is corrosion of the index shaft and bearings. MicroPulser uses high performance low friction lubrication free engineered-plastic bearings and a stainless steel index shaft to eliminate corrosion failures. MicroPulser provides two Class I, Division 1, Groups C and D outputs. Clockwise and counter-clockwise for the model MP-1000, or two matched outputs for connecting to two devices at the same time such as custody transfer) for the MP-1000M. The high resolution output is produced by a dual channel optical detector and a precision slotted disk. A microcontroller monitors the detector to determine the rotation direction as well as angular movement. The direction information is used by the controller to determine the True Absolute Rate and remove false pulses produced by vibration.
