Pulse counters with m-bus/modbus

лю-bus (Meter-bus) is a new European standard for remote reading of tax instruments and different types of sensors. The reading is accomplished by several different methods - from direct reading of current indication of the instruments to fully remote reading of all devices in the net by GPRS technology. The use of M-bus interface allows fully electronic reading of data with all the benefits of it.

Pulse counters with m-bus are slave devices in the network, intended to connect all devices, which do not have m-bus interface, but pulse output instead. Tax devices with pulse output are relatively cheap and wide offered on the market. They can be water-, heat-, gas- meters, etc. Pulse counters collect information from these devices (count pulses), and save it in internal memory. On the other hand, pulse counters have m-bus interface, which provides them with power supply and information channel. Additional rechargeable battery is provided, to assure that no data loss will occur, if for some reason m-bus network failed. This battery can provide up to 96h work time w/o main power supply for MBCS/MBSS and 40 days for MBHS. When m-bus is up and running again, the battery recharges to its maximum capacity.

General information

We produce m-bus and modbus pulse counters, which are fully compatible with the specifics of bulgarian civil buildings. M-bus counters are powered from m-bus net and no other external supply is needed, which greatly eases their mounting. Modbus counters are intended for 220V AC power supply. There is no need of maintenance and cleaning. Every pulse counter has embedded accumulator rechargeable battery (except MBHS where this is an option). That way the devices can work for three months even if there are problems with the main power supply or m-bus network. We guarantee 10 years of reliable work - this is the time, in which the battery will keep its quality. The counters have 2/4/6/8 inputs, counting simultaneously. Though there can be count energy meter, heat meter, cold and hot water meter, which in most cases is enough for one point of the net. This way we minimize the price of the device. Furthermore, we offer a variant without LCD display, which is the low-cost solution. If one uses variant with LCD display, he can see in every moment pulses collected for each input and tariff, cost value and other useful information.

Security

Caution has been taken to prevent any eventual attempts for manipulating data. For this purpose pulse counters do not allow main parameter changing - except the first and only set-up of unique net address. It is not allowed to write in the internal memory via m-bus net, the user can only read the number of pulses of every channel. Some of the counters allow different ID numbers to set to each input, but more information detailed sections, dedicated to m-bus counters type.
