MODEL BC-200A PUMP STROKE COUNTER

MODEL BC-200A PUMP STROKE COUNTER

The pump stroke counter is used for measuring the number of pump strokes and per minute number of pump strokes (i.e. the frequency of pump strokes) of a reciprocation mud pump so to provide for the drill operators an accurate adding amount and speed of the mud to be grouted into a well shaft. It is a necessary meter in drilling process. Model BC-200A pump stroke counter comes out from improving the model BC-100 pump stroke counter, being a kind of updating and upgrading product of BC-100 pump stroke counter. Compared with BC-100, it increases a signal input channel and increases the functions of the count and accumulation of the pump strokes of a single channel, the total accumulation of the number of pump strokes, data memory when the machine is turned off, etc. Also its operation is even more convenient, simple and reliable. The totally enclosed structure, water-proof signal connectors and keys endow the BC-200A pump stroke counter with good moisture-proof and water-proof performance. After being subjected to a water-proof test for 12 hours under water with a depth of 1m, the BC-200A pump stroke counter shows so good water-proof performance that no water is found entering in. furthermore, with its overall power consumption being around 150uA, its sensor signal current around 5uA, the BC-200A pump stroke counter is actually explosion-proof, that is, it is intrinsically safe.
