The OMNI FLOWMETER COMBO BOARD Type E/ED serves as a high-performance, multi-function interface designed for the OMNI 3000E and 6000E series flow computers. It excels in high-accuracy measurement by supporting advanced pulse fidelity and double chronometry, making it the primary choice for custody transfer applications and complex prover loop installations where signal integrity and rapid data processing are critical for fiscal accountability.

Model Comparisons
The Type E/ED 10600801 is specifically designed for the “Enhanced” (E-Series) OMNI systems, whereas the Type A/B 10600601 is typically found in standard OMNI 3000/6000 legacy units. While the Type A/B board provides reliable general-purpose measurement, the Type E/ED 10600801 offers superior hardware support for Level A Pulse Fidelity (as per IP 252/76) and is required for systems utilizing advanced prover software features. Additionally, Type E modules feature improved signal return management for shared turbine/PD meter inputs, reducing potential interference in high-density rack configurations.
Operating Tips
- Terminal 7 Jumpers: When multiple E-Type combo modules are installed, all “Pin 7” terminals must be connected together to ensure a common signal return for the detector switches and prover inputs.
- Prover Synchronization: If using this board for prover operations, verify that the master meter method is correctly assigned in the firmware, as Type E boards are often hard-coded to prioritize Meter 4 as the Master Meter in specific OMNICOM configurations.
- Input Thresholds: This board has a standard input threshold of approximately 3.5V; if using a low-voltage pickoff coil, a pre-amplifier must be used to ensure the pulse train is correctly registered by the 10600801’s high-speed counters.
