Single Phase Site Energy Meter Test Instrument Type KP-P1001-A
Bofa Instrument & Equipment Co., Ltd
Single phase site energy meter test instrument type KP-P1001-A (without voltage and current source) is an ideal instrument to test all kind single phase energy meters accuracy below 1.0, especially for meters on site. During tests, the tested meter must be on load condition (that means the tested meter must be working). The instrument tests the errors by comparing energy impulse from the tested meter with energy impulse from the reference meter inside the instrument.

Rotational Flow Demonstration Kit
The rotational flow demonstration kit detects the rotational position using the MCU’s on board data transfer controller (DTC) function, a form of state machine, while the MCU’s core is in stop-mode state. This ensures that the average power consumption is kept as low as possible, with IAV (average current) at 4.5 microampere (μA) and a 32 sample burst per second. The flow demonstration kit senses the flow direction and volumetric flow rate of water and gas, and can also detect reverse flow. The demonstration kit is applied using an active inductive method. Two coils are used to sense the rotational position of a part-metalized disk, and a third coil is used to generate a reference signal.
