Heinrichs Flow Meter Catalog: Metal Tube Variable Area and Coriolis Transmitters for Heavy Industry
Quick Answer: This catalog covers metal tube variable area meters and Coriolis transmitters for heavy industry. These devices handle aggressive fluids, high pressure, and high temperature. Send your flow range, pressure, temperature, and pipe size to Silver Automation Instruments for a specific quote.
What Is in the Heinrichs Flow Meter Catalog
The Heinrichs Flow Meter Catalog: Metal Tube Variable Area and Coriolis Transmitters for Heavy Industry groups two main flow technologies. One group is metal tube variable area meters. The other group is Coriolis transmitters. Both groups suit heavy industry. Engineers use them in chemical plants, oil and gas facilities, food processing lines, and marine systems.
Metal tube VA meters from this range are not glass tube rotameters. They have a metal body and a conical float. They handle higher pressure and higher temperature. In practice, we see them on auxiliary lines, purge lines, and small skids. A paint manufacturer in Southeast Asia ordered DN15 metal tube VA meters for solvent batching. The process pressure was 12 bar and the operating temperature was 90 °C.
The Coriolis transmitters in the Heinrichs catalog cover mass flow and density. They give direct kg/h readings. Some models have PT100 temperature sensors built in. Output options include 4-20 mA HART. ATEX Zone 1 models appear for hazardous areas. A customer in Vietnam asked us for a Coriolis transmitter for fuel oil blending at 140 °C and 8 bar. We quoted a unit with stainless steel wetted parts. Mass flow range was 0 to 3000 kg/h.
Metal Tube Variable Area Meter Details
Metal tube VA meters work for fluids that would break a glass meter. They suit high pressure gas, hot oil, steam condensate, and aggressive chemicals. The catalog lists sizes from DN15 to DN150. Process connections range from threaded to flanged. Maximum pressure ratings can reach 40 bar depending on the model. Temperature limits often range from -80 °C to 300 °C.
Here is the thing. Most engineers skip the float material selection. But the float material matters. 316L stainless steel is common. PTFE coated floats work for acids. Hastelloy floats fit some chlorinated fluids. We have seen a water treatment site in Saudi Arabia use a DN25 metal VA meter for dosing coagulant. The flow range was 30 to 300 L/h. The customer needed a local indicator plus a 4-20 mA transmitter for remote monitoring.
Because heavy industry often has vibration, the pointer and scale need to be clear. Some models have magnetic coupling. This design removes a mechanical seal. That reduces leak points. We usually recommend local indication plus 4-20 mA output when the meter is on a fuel skid or a burner line.
Coriolis Transmitters in Heavy Industry
Coriolis transmitters measure mass flow directly. They also measure density and temperature. Typical accuracy can be ±0.2 percent of rate. Some catalog models go better. These meters are useful for honey, fuel oil, syr

Heavy industry has tough conditions. Coriolis transmitters in the Heinrichs catalog include remote transmitter versions. A remote transmitter helps when the pipe is hot or when space is tight. Process temperature can reach 200 °C on standard models. High temperature versions go higher. Pressure ratings vary from PN40 to PN100. Wetted parts include 316L, Hastelloy, and titanium for seawater or acid applications.
We saw a desalination plant in Oman ask about a seawater flow meter. The pipe size was DN50. The salinity was high. The brine conductivity was around 52000 µS/cm. We recommended a Coriolis transmitter with titanium tubes. That avoided corrosion. The output was 4-20 mA HART. The plant also needed density measurement to check brine concentration.
How to Read the Catalog Number
The Heinrichs catalog uses a model code system. The metal tube VA meter code defines size, material, connection, and output. The Coriolis transmitter code defines wetted parts, process connection, electronics, and approvals. Engineers should check the code against the process data sheet. We often help customers decode these options before they order.
Send us your fluid name, viscosity in cP, flow range, pressure in bar, temperature in °C, and pipe size in DN. We will suggest a model code. This cuts quoting time to one day in most cases.
FAQ
Does Silver Automation Instruments supply Heinrichs metal tube VA meters?
Yes. We supply metal tube variable area meters and Coriolis transmitters for heavy industry. Send us the model code or process data and we will quote.
What is the difference between a glass tube rotameter and a metal tube VA meter?
A glass tube rotameter suits low pressure and clean fluids. A metal tube VA meter has a metal body. It handles higher pressure, higher temperature, and dirty or hazardous fluids.
Can Coriolis transmitters measure gas flow?
Yes. Coriolis transmitters measure gas mass flow directly. You need to check the flow range and density. Low density gas needs a larger meter or a special model.
Do these meters work in hazardous areas?
Many models in the Heinrichs catalog have ATEX Zone 1 and Zone 2 approvals. Specify the gas group and temperature class when you ask for a quote.
What output options are common?
4-20 mA HART is common. Some models support pulse output and Modbus. The Coriolis transmitters often include density and temperature signals on the same loop.
