Voltmeters

A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit.

Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a galvanometer and series resistor. Meters using amplifiers can measure tiny voltages of microvolts or less. Digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter.

Ammeters

An ammeter (abbreviation of Ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in Amperes (A), hence the name. The ammeter is usually connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured.

MultiMeter

A multimeter is a test tool used to measure two or more electrical values - principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.

Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance.

Bluetooth Battery Monitor

Victron BM-712 Battery Monitor

The BMV-712 is a high precision battery monitor. The essential function of a battery monitor is to calculate ampere hours consumed and the state of charge of a battery. Ampere hours consumed are calculated by integrating the current flowing in or out of the battery

Battery ‘fuel gauge’, time-to-go indicator, and much more

The remaining battery capacity depends on the ampere-hours consumed, discharge current, temperature and the age of the battery. Complex software algorithms are needed to take all these variables into account.
Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power consumption in Watts.
The BMV-712 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage (see below).

Bluetooth Smart

Use the Bluetooth Smart dongle to monitor your batteries on Apple or Android smartphones, tablets,macbooks and other devices.

Easy to install

All electrical connections are to the quick connect PCB on the current shunt. The shunt connects to themonitor with a standard RJ12 telephone cable. Included: RJ12 cable (10m) and battery cable with fuse (2m);
no other components needed. Also included are a separate front bezel for a square or round display appearance, a securing ring for the rear
mounting and screws for the front mounting.

Easy to program (with your smartphone!)

A quick install menu and a detailed setup menu with scrolling texts assist the user when going through the various settings. Alternatively, choose the fast and easy solution: download the smartphone app (Bluetooth Smart dongle needed)

Midpoint voltage monitoring (BMV-712 only)

This feature, which is often used in industry to monitor large and expensive battery banks, is now for the first time made available at a low cost, to monitor any battery bank. A battery bank consists of a string of series connected cells. The midpoint voltage is the voltage halfway along the string. Ideally, the midpoint voltage would be exactly half of the total voltage. In practice, however, deviations will be seen, that depend on many factors such as a different state of charge for new batteries or cells, different temperatures, internal leakage currents, capacities and much more. Large or increasing deviation of the midpoint voltage, points to improper battery care or a failed battery or cell. Corrective action following a midpoint voltage alarm can prevent severe damage to an expensive battery. Please consult the BMV manual for more information.

Standard features

BMV-702 additional features

Additional input to measure voltage (of a second battery), temperature or midpoint voltage, and corresponding alarm and relay settings.

BMV-700H: 60 to 385 VDC voltage range
No additional parts needed. Note: suitable for systems with grounded negative only (battery monitor is not isolated from shunt).

Blue Sea Digital Multimeter with Alarm

The 8200 Series meters incorporate microprocessor control and advanced electronics specifically designed for power monitoring to provide accurate metering with a variety of adjustable user features. DC meters have the provision for separate power and voltage sensing. Using separate voltage sensing is recommended to minimize the voltage drop caused by the current consumption of the meter itself. This is particularly necessary if the meter is located more than a few feet from the battery or source being measured. Models that have the ability to measure DC current come with a precision shunt. The shunt must be installed in the negative line to avoid damage to the meter. The shunt is a
precise resistance that is temperature stable. It has a full current rating of 500 Amps and when 500 Amps flows it generates a voltage of 50 mV (0.050 V). Thus, 10 Amps generates 1.0 mV, 1 Amp generates 0.1 mV, and 0.1 Amp generates only 0.01 mV. This is a very small signal and you must be sure that all connections are secure and well made. It is also necessary to use twisted pair wire to minimize susceptibility to electrical system noise.

A 12 volt supply is required. These gauges only draw 50 mA so they can be left on without flattening your on-board battery.

There is a power on/off switch to turn the gauge off when the caravan is not in use.

The gauges can be matched with 2.5 metre, 5 metre or 7.5 metre lead sender probes*

The LCD water gauge measures H108mm x W108mm x D20mm.

The easy to fit tank sender probe only requires one 22mm hole in the side of the tank and suits tanks from 100mm to 280mm deep.

The sender probe is sealed by a special grommet which is compressed in the hole when the nut is tightened and measures the water level by contact with the 5 sensors along the arm. It has no moving parts.

DC Analogue Meters

Blue Sea DC Analogue Voltmeters

Micro and Standard size meters with backlighting for low light conditions.

There is no activity that will contribute more to a healthy electrical system than proper battery management. Using a voltmeter to measure open circuit voltage measures the potential charge of your battery.

Since the difference between a fully charged battery and a fully discharged one is only 1 volt in a 12v system, the meter must have good resolution and accuracy.

Blue Sea DC Analogue Ammeters

The Full Scale ammeters meters show either load draw or charge amperage going into the battery.

They will give you an accurate reading, some units also feature internal shunts with the higher amperage units using external shunts available separately.

The Zero-centre ammeters show the total load/charge amperage on the battery.

These meters will give you an accurate reading of what is going in/out of the battery at a glance.

No more looking at your charge meters, then also at your load meters, then adding together to get the total from your battery, those days are a thing of the past.

Blue Sea Systems Ammeters of 50 Amps and greater capacity utilize an external shunt as the current sensing device.

This shunt can be located in the wiring system to permit the shortest and most direct path between the source and the load. Small gauge wires connect from the shunt to the meter, which can be located conveniently for viewing.

ARRID Expanded Voltmeter

These voltmeters are wired in parallel with the battery to measure voltage.

Nothing is more annoying than buying a panel mounted volt meter and needing a magnifying glass to see where the needle on the scale is. The people at ARRID have realised this and made these meters especially for this purpose. They are made to show the scale that the battery will be in therefore giving a higher resolution scale. This gives you a more accurate reading of what the voltage in your system is. Simple two (2) wire installation, wired in parallel with the battery.

ARRID Volt & Amp Panels

Thinking about adding some Volt Meters/Ammeters into your system, well look no further than these stylish panel meter mounts. Made out of a strong 2.5mm alloy laser cut plate to fit 2 ARRID meter panels, either horizontally, or vertically. This only requires one large hole to be cut in the desired position, rather than 5 holes per meter. These panels therefore drastically reduce the time and headaches of installing the meters.
