Octave Ultrasonic Water Meters
Octave Ultrasonic Water Meters
A revolutionary, precise and ultra reliable ultrasonic bulk water meter with no moving parts.With superior hydraulic and batteries that last up to 15 years, the Octave is today’s best choice in bulk meters for Utilities, Waterworks, Industrial and Agricultural applications.

ACL Coaxial Valves
Coaxial Valves
Compared with conventional valves coaxial (or coax valves) use significantly fewer components leading to robust, highly reliable designs. At the same time the simplified more linear flow path through a coaxial valve gives superior flow rates when compared to conventional solenoid valves.

ACL’s have expanded their range of high pressure solenoid valves for air or water comprise three models capable of controlling pressures of up to 150 bar.
Plastic Solenoid Valves
Plastic Solenoid Valves
Wide range of plastic solenoid valves for use with water and steam, fitting styles include threaded, John Guest push-fit and hosetail. Threaded sizes from 1/8" to 3" BSP(G).
Vending Solenoid Valves
Vending Dispense Valves
Beta Valve has manufactured solenoid valves for the vending and drinks dispense industry for over twenty five years. Since 1991 we have produced our own range of dry-armature dispense solenoid valves for both hot and cold water applications.
Water Meters from Arad
Water Meters from Arad
Our range of high quality water meters are produced by Arad. Every meter is individually tested and inspected to ensure quality and reliability. Many of Arad's water meters are MID certified for use in the European Union and a number have been tested and approved to WRAS standards. In sizes from 1/2" to 12" all of Arads' industrial water meters are available with an optional electrical output for connection to process control, data logging or BMS equipment.

Ultrasonic measuring Technology 

The Arad Group has developed a dual beam ultrasonic solution called Sing Around. 

Sing Around was developed to meet the market's requirement for improved measurement accuracy of water flow.  This innovative technology is integrated into all Octave ultrasonic flow meters manufactured by Arad. 

The two sets of sensors send sound pulses diagonally across the water flow path from one side of the meter to the other. The system measures the total time it takes to complete one hundred loops with the water flow and against the flow, then subtracts one from the other, thus deriving an average, which is highly accurate.

Sing Around offers the following advantages:
  * Extremely high accuracy.
  * Wide flow range.
  * Stable measurements.

By developing the innovative Sing Around dual beam technology, Arad Group has set the industry's benchmark for accuracy across extremely wide flow ranges(Q1 to Q3 flow rates), endowing most Octave meters with a Q3/Q1 ratio R of 500. Making the Octave flow meters both sensitive and accurate at high and low flow rates means a single compact Octave ultrasonic flow meter can be used as a replacement for old style mechanical double flow meters where a large Woltman (turbine) meter is connected in parallel with a smaller Multijet meter - the Woltman meter handling the high flows and the Multijet meter measuring the small flows.

The use of a single ultrasonic flow meter offers obvious advantages when considering installation, calibration and maintenance.


Extensive Choice of Output Options

Octave flow meters can be specified with a number of different output configurations. 

Analog Output    
Shows the instantaneous water flow rate. The Analog Output is a 4 - 20 mA current loop (the end user must supply power to the unit).
The Analog Output is programmable for forward and reverse flow.
 
The 20mA point can be programmed to any flow rate lower than the maximum flow of the meter.

Digital (pulse) Output    
The Digital (pulse) Output is an open drain transistor output that provides pulse per quantity with these options:
1. Two scaled forward and/or reverse mode pulses
2. One scaled forward pulse and one alarm frequency output
3. Measuring units of the output can be programmed different than displayed units.

Pulse resolution will be shown on the display for each pulse separately

Dry Contact Output    
The Dry Contact Output is a dual mechanical relay output that provides pulse per quantity with these options:
1. Two scaled forward and/or reverse mode pulses
2. One scaled forward pulse and one alarm frequency output
3. Measuring units of the output can be programmed different than displayed units.

Pulse resolution (k factor) will be shown on the display for each pulse separately, an onsite power supply of 5-35 VDC is needed.

SSR (Solid State Relay)    
The SSR is a dual electronic relay output that provides pulse per quantity with these options:
1. Two scaled forward and/or reverse mode pulses
2. One scaled forward pulse and one alarm frequency output
3. Measuring units of the output can be programmed different than displayed units.

Pulse resolution will be shown on the display for each pulse separately

Arad Gladiator domestic water meter
Super Sensitive Water Meter for UK
The Gladiator is Arad's proven highly accurate rotating piston type positive displacement water meter. Flowing water causes the piston to rotate within its chamber, each piston revolution being equivalent to a known volume of water. The piston movement is transferred by a magnetic coupling to the register. The concentric mounting version of the Gladiator UK is tailor made for the UK market.
