Technical Data Overview for CODA-Series Mass Flow Controllers

Specifications: The CODA-Series Mass Flow Controllers are designed to handle flow rates from 40 to 100,000 grams per hour. They operate within an ambient temperature range of 0–60°C and a fluid temperature range of −35–70°C. The devices offer ingress protection of IP40 or IP67 and are constructed with 316L stainless steel, FKM, and FFKM materials, with optional EPDM or PCTFE.

Sensor and Control Performance: The mass flow accuracy for liquids is ±0.2% of reading or ±0.05% of full scale, while for gases it is ±0.5% of reading or ±0.05% of full scale. The repeatability is ±0.05% of reading or ±0.025% of full scale. The steady state control range is 2%–100% of full scale, with a density accuracy of ±5 kg/m³ and a measurable density range of 100–2,000 kg/m³. The viscosity range is 0–200 cP.

Temperature Sensitivity: The mass flow zero shift is ±0.01% of full scale per °C from tare temperature, and the mass flow span shift is ±0.005% of reading per °C from 25°C.

Valve and Response Times: The valve function is normally closed. Typical control response times are <500 ms for 40 g/h–10,000 g/h and <800 ms for 30,000–100,000 g/h. Indication response times are <100 ms for 40 g/h–10,000 g/h and <200 ms for 30,000 g/h–100,000 g/h.

Communications: The controllers support analog I/O options of 0–5 Vdc, 0–10 Vdc, and 4–20 mA, as well as digital I/O options including Serial (USB-C), RS-232, RS-485, Modbus RTU, EtherCAT, and EtherNet/IP. Power requirements vary with flow rates, with 4 W for 40–10,000 g/h and 5 W for 30,000–100,000 g/h, both at 9–30 Vdc.

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

Dimensions and Weight: The dimensions and weight vary by flow range. For 40–10,000 g/h, the dimensions are approximately 4.318 in height, 5.138 in width, and 1.122 in depth, with a weight of about 2.0 lb. For 30,000–100,000 g/h, the dimensions are approximately 5.304 in height, 5.945 in width, and 1.575 in depth, with a weight of about 3.0 lb.
