М-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.

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.
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.
