Alicat Coda KF and KG Series

  • Flow rate of up to 100kg/hour
  • Highly precise measurement to ±0.2% of reading
  • 2-100% control range of full scale

Alicat Coda KG series is an integrated system combining a CODA meter and a gear pump to create and control flow in a previously unpressurised system.

Alicat Coda KF series is a standard Coda Coriolis flow meter with the added functionality of PID control. The integrated PID control allows easy integration with your existing liquid pump allowing for full pump automation with separate PID control

Flow rate

Full scale flow rate is possible from between 1kg/hour up to 100kg/hour with a steady state control range of 2-100% of full scale. A range of liquids are compatible and are precisely measured at an accuracy of ±0.2% of reading.

Densities and Response time

Densities can also be measured between the ranges of 100 to 2000 kg/m3 with a density accuracy of ±5kg per cubic meter. Batching and dosing comes built in enabling it to be used in a range of sectors such as chemical mixing or adding dyes and fragrances to laundry detergents and fabric softeners.

The impressive control response time is less than 1500ms with an indication response time of less than 60ms.

Temperature and Pressure

Operating temperature range can be from as low as -35°C up to 70°C with an ambient temperature of between 0 and 60°C.

Inputs and Outputs

Digital input and outputs are ASCII and Modbus RTU over RS-232 or RS-485. Three analog input and output options are available being 0-5Vdc, 0-10Vdc and 4-20mA with an analog update rate of 50Hz.


Wetted materials are 316L stainless steel, PEEK and FKM as standard with the option for nickel alloy and FFKM. It has been given an ingress protection rating of IP40.
