FIEDLER AMS - Model H1 -Hydro Logger

• Pulse inputs for connection of OPTO and REED water meter sensors.
• Current inputs for pressure and water level sensors in Water reservoirs and pumping stations.
• Binary inputs (flooding, running of pumps)
• Data GSM/GPRS transfers into the server
• Integrated warning SMS messages system
• Operating time of the battery is up to 5 years without its changing, input for external power supply 12VDC
• Parameters configurable via the Internet
• Robust enclosure wiht High Protection IP67
• Low operating costs

• Remote water meters reading. Monitoring of instantaneous and minimal night flows.
• Continuous monitoring of flows, pressures and water levels in shafts and storage water tanks.
• Development of udometric and stream gauge stations with possibility of warning SMS sending.

H1 has a graphic screen for a rapid summary of measured values (flow, pressure, water level, temperature, status of binary channels, battery voltage, currency in the connected sensors, temperature and humidity inside the device, etc.). Aslo, the screen makes easier instalation of GSM anteane in outdoor - the screen displayes the intensity of GSM signal and the total data transfered into the server.

Own battery designed for several years of running. This battery can be spared by connecting of external power supply 8-15VDC. A very low quescent current of this external power supply (50uA) and high effectivity of build-in converter allows  to use a small 12V accumulator for spared power supply.

Another build-in programable voltage changer (output current 6V or 15V) allows easy connection of two pressure or wate level sensors whith output signal 4-20mA. Power supply current of these sensors is monitored. When the current is increased, user is noticed about possible sensor failure.

Hydrologger H1 has a separate power terminal where battery voltage is permanently present for power supplying of OPTO sensors.  Also, the current for OPTO sensors is monitored and its value is archived.

Great capacity of data memory saves measured data within years of battery running and also in a case of battery flat. When the data memory is full, the oldest data are cyclically rewrited.

H1has a robust mechanical design with High Protection cover IP67, which is necessary for placing in a permanently humid environment of storage water tanks, water treatment plants and shafts.

A stainless steel holder (for atachement of H1 on the wall) and GSM mast antenna are included in a price of Hydro logger H1. It is possible to order several dB graduated antennae for device installation in underground shafts and in places where is weak signal. Also, you can order an antenna extension cable.

Measuring A channels (for analogue variables)

Hydrologger H1 has 8 measuring channels for recording in 16-bit resolution. Each recording channel can have its own specific name, number of decimal places for measurement and archiving, units, method of measurement and many other parameters. The frequency of archiving is adjustable separately for each recording channel. After getting over set limits (limit alarm) or after quck change of values (gradient alarm), the station data logger enables to display more often record of selected values.

Binary B channels (for running and failures)

Up to 8 binary channels for recording of the time when the pump failure begins and ends, pump running time, information about entrance to the building, and other events that can be signalised by binary input switching on or off.

Checking C channels

Checking channels for recording of battery voltage, size of external power supply voltage, current took by connected sensors, sensores of temperature and humidity inside the data logger were newly added.

Inputs

PV1-PV2: 2 quick inputs with integrated pulses counters for OPTO or REED sensors.

PV3-PV4: 2 Pulse-binary inputs for REED sensors or like inputs of binary states (runing or failure of pumps, flooding of reservoirs, security guard, etc.)

AV1- AV2:  2current inputs, analogue signal 0-20 mA, 4-20 mA, 1-5 mA, 0-5 mA, 0-1 mA. Variation: 2 voltage inputs from 0 to 2,0V.

RS-485: Serial network interface for connection of separate measuring probes (e.g. US1200 - ultrasonic water level sensor).

HYDRO LOGGER H1 is equiped by combinated sensor which monitors temperature and humidity inside the device.
