DOC-SPECS-KCO · REV 1, 10 May 2021 1 ⁄ 2Technical Data for CODA KCO-Series Mass Flow Controllers

Product catalog summary

Overview: The document provides technical specifications for the CODA KCO-Series Mass Flow Controllers, which handle flow rates from 40 to 100,000 grams per hour. It includes details on mechanical, sensor, control performance, communications, and range-specific technical data.

Mechanical Specifications: The operating temperature range is 0–60°C for ambient and −35–70°C for fluid. The ingress protection is either IP40 or IP67. Wetted materials include 316L stainless steel, FKM & FFKM, with options for EPDM or PCTFE.

Sensor and Control Performance: Mass flow accuracy is ±0.6% for liquids and ±1% for gases. The repeatability is ±0.1% of full scale, with a steady state control range of 5%–100% of full scale. Density accuracy is ±5 kg/m³, and the measurable density range is 100–2,000 kg/m³. The viscosity range is 0–200 cP.

Communications: The controllers offer analog I/O options (0–5 Vdc, 0–10 Vdc, 4–20 mA) and digital I/O options (Serial and Modbus RTU over RS-232 or RS-485, EtherCAT, EtherNet/IP). Electrical connections include USB-C, DB-15, M12, and RJ45.

Range-Specific Technical Data: The document details process connections, recommended inlet filters, nominal pressure drop, and proof pressure for different flow ranges. For example, a 40 g/h flow uses a 1/4″ VCR®-compatible male connection with a 2 μm filter and ≥6 PSID pressure drop.

Dimensions and Weight: Dimensions vary based on flow scale, with the 40–10,000 g/h models measuring approximately 4.318 in height and weighing about 2.0 lb. The 30,000–100,000 g/h models are larger and heavier.
