GFC319 is a steam flow computer in DIN 96x96 mm enclosure with very high accuracy and variety of inputs and outputs.


Isolators

A new range of analog signals isolators and splitters has been released. Passive or active, 0-20 mA, 4-20 mA, 0-5 V, 0-10 V, 1-5 V, 2-10, DIN rail mount, small size, high isolation and accuracy make them the perfect solution for ground loop and noise problems in any application.


Remote Displays

GRD101 remote display now has a new version GRD101-BR that accepts bridges, load cells and other differential millivolt signals. It provides very accurate and stable 10.000 V DC to the bridge (load cell).


Flow Computers for Steam

GFC300 and GFC301 flow computers now calculate and display enthalpy, heat rate, net heat, delta heat and heat total of steam. The outputs can also be controlled by these variables. A large variety of units for them can be chosen.


Pulse converters / linearizers

GPC5K has a 30 point calibration / linearization table and an isolated output which frequency is related to the input frequency through the 30 point table. This way GPC5k can be used, for an instance to linearize and isolate flow meters. The output can be 5V square wave or open drain.


Flow Computers For Petroleum Products

GFC201 uses API tables 24B, 24D, 54B and 54D, measure accurately temperature and compensates the volume of the liquid. It has a 10 point calibration curve, isolated pulse output, isolated 4-20 mA output and isolated second digital output that can be programmed to be RTD alarm or rate alarm. GFC201 calculates and displays nett rate, gross rate, nett total, gross total, temperature or error number if something in the RTD circuitry is wrong.


Conductivity Transmitters

GCT100K-MB has a high accuracy in the entire range of 0 to 100 000 uS/cm, RS485 MODBUS RTU, 1 uS/cm resolution, baud rates up to 115 200, single temperature coefficient or 10 points curve. All settings are field programmable.

GCT100K has a high accuracy in the entire range of 0 to 100 000 uS/cm, isolated 4-20 mA output, 1 uA resolution, single temperature coefficient or 10 points curve. All settings are field programmable.


Conductivity Switch

GCS20K is a conductivity switch with 100V / 1A open drain output, programmable threshold, hysteresis and alarm delay.


Digital Isolators

Our new line of digital isolators have a very small size, slim design, high functionality and isolation.

GPi11 is a pulse isolator.

GPi12 is a pulse splitter.

Both are DIN rail mount, their outputs have no polarity and can equally switch DC or AC current. The input voltage has a very large range and they can also be used like solid state relays for ON / OFF control of loads up to 24 W.


pH, REDOX / ORP, Dissolved Oxygen, mV, thermocouples

Our new line of RS485 MODBUS RTU transmitters is a special design for pH, REDOX / ORP, dissolved oxygen mV and thermocouple signals.

GpH140-11 has two inputs with an extremely high impedance, specially designed to measure pH and / or REDOX / ORP.

GpH140-12 has one input for pH / REDOX / ORP and one for mV / thermocouples.

GpH140-22 has two inputs for mV / thermocouples.

All of them have as a standard one Pt1000 RTD input, the built-in cold junction compensation and one 4-20 mA two wire loop power input.


Flow Computers For Irrigation

Our new line of flow computers is a special design for irrigation. All of them measure accurately and display flow rate with input pulses down to one pulse every 5 minutes.


New Line Of Panel Mount Flow Computers

All GFC100/200 series flow computers / totalizers now have a panel mount version in DIN 72x72 mm with IP65 (NEMA-4) protection.


GMAG100 improvements

A new version of GMAG100 has been released.
Now it has larger range of baud rates and programmable stop bits.


GFC111-MB and AH111-MB

GFC111-MB and AH111-MB Now they have up to 5 programmable decimal places, total up to 9 digits (1 billion), larger ranges of baud rates, programmable stop bits and other improvements.

GFCP111-MB and AHP111-MB - the panel mount versions, have been released.


Conductivity Transmitters

GCT20K and GCT20K-MB now have a programmable 10 points curve for the temperature coefficient. Switching between a single TempCo and the curve can be done at any time in seconds.

GCT20K-MB conductivity transmitter has been released. It is field programmable, with RS485 MODBUS RTU, high isolation, high accuracy, flexibility and reliability.

GCT20K conductivity transmitter has been released. It is field programmable, with an isolated loop power 4-20 mA output, high accuracy, flexibility and reliability.


Universal input power supplies

GPS122D, GPS123D and GPS125D power supplies have been released. They have a second isolated output providing 24 VDC / 42 mA. It can power the isolated analog outputs of our flow computers, loop power devices or just other devices that need to be isolated.


Flow Computers for Liquids

GFC100/200 series Flow Computers
GFC301 wall mount IP65 (NEMA-4) dual channel flow computer for liquids, gases and steam is released. Batch functionality has been added to each channel. The analog output (when 4-20 mA loop power) works from 7.0 V allowing up to 250 ohm load on a car / truck battery. All options for the analog output have a lot higher accuracy and resolution.
