Flow Meter Installation type has various types such as inline flow meter, insertion flow meter, clamp-on flow meter, open channel flow meter. Before discussing the type of flow meter installation, let’s discuss the definition of flow meters as follows.
Definition of Flow Meter
A flow meter is an instrumentation device used to measure the flow of a fluid in a closed or open system such as a trench or river. In connection with the many types of flow meters available and applications in the field, there needs to be criteria for choosing a type flowmeter. In order to choose the type of flow meter meets the purpose of installation of flow sensors, both in terms of function and accuracy. Because this will be related to the amount of investment costs, operational costs and maintenance costs.
The selection of the type of flow meter that is based on the way of installation, has an important role to reduce all types of costs above. Therefore, before determining the type of flow meter purchased it is good to consider the type and model of the flow meter of the installation type.
In terms of choosing the type of flow meter that needs to be considered is the optimal value and not maximal. Referring to the results of production, the demands for efficiency, quality stability, cost down and others are more important because of intense competition.
Therefore, when determining the type of flow meter, what needs to be considered is the type of flow meter that has optimal benefits and not maximal. The point is, choose a flow meter that has accuracy as needed and do not overdo it. Use this type of flow meter installation as a consideration of small maintenance costs or approaching free maintenance.
Use a flow meter whose cost and installation time are as cheap and short as possible if necessary do not have to stop the production prose process. Furthermore, please continue with consideration in accordance with the design of the engineering.
Types of Flow Meter Installations
Inline Flow Meter
As we know the type of in line flow meter is the most widely known and used type of flow meter. Almost all types of flow meters have an inline installation system that is applied to liquids and gases.
The installation system of the type of inline flow meter is done by cutting the pipe. While the connection system can use thread, flange, triclamp or sanitary clamp, wafer, or welding. Insertion Flow Meter
Insertion flow meter is a type of flowmeter whose installation is done by perforating the pipe to enter the sensor into the pipe. Next installed fittings so that they can occupy the flow meter sensor into the fittings that are reinforced with nuts, slotting or pins key.
Clamp-on Flow Meter
Flow meter clamp on is a type of flow meter whose installation method does not cut pipes or perforate pipes. Clamp on flow meter uses sensor components of the type of ultrasonic that is often called ultrasonic transducer. The working principle of this ultrasonic clamp on flow meter is by measuring the speed of fluid flow, using ultrasound so that with calculations on ultrasonic transmitters the volume that flows can be read.
Using ultrasonic sensors it can measure the average speed of fluid flow in a pipe. The measurement results are average due to the time difference between signal delivery and signal reception with unidirectional or opposite flow.
Clamp on flowmeter is how it is installed and how it works is almost the same as portable ultrasonic flow meter. The difference is that this flow meter uses power that is fixed and used for long operations or production. As the flowmeter for production purpose is to read and store the results of the flow totalizer reading.

In general, flow meter clamp on has an analag output of 4-20 mA, alarm, relay, pulse or communication RS232 or RS485. As for the type of flow transmitter or ultrasonic flow computer there is a type of wall mount, pannel mount or pipe mount. According to the power supply, some use AC 220 VAc or 24 Vdc or solar cells.
Clamp on flow meter type is only owned by Ultrasonic Flow meter and for this type there are two models according to its function. The two models are portable flow meter and wall mount clamp on fix ultrasonic flow meter. As for the portable type there is a hand held and there is a portable one.

Open Channel Flow Meter
There is also a type of flow meter that can be applied to channels such as river flows and trenches where the flow of water is in open channels, whose flow is generated by the difference in height, namely gravitational flow. For this type of open channel flow meter uses a combination of flow velocity and cross-sectional channel area measured with height sensor or meter level.
Open channel flow meter is a flow meter that can be applied to measure flow in open channel systems such as canals, rivers or trenches. Basically this open channel flow meter calculates the flow speed taking into account the height of the surface.
For the measurement of flow speed can use transit time flow sensor or magnetic flow sensor. As for the surface height of the flow using ultrasonic level sensors. Magnetic flow sensor here serves as a sensor to measure flow velocity combined with meter level sensor, it will get flow rate and volumetric from liquid flow on the open channel.
In addition to using magnetic sensors to read and know flow velocity can also be used. Ultrasonic flow sensor type is both dopler type and transit time ultrasonic flow sensor type. Like magnetic sensor users, ultrasonic sensor is tasked to calculate flow velocity combined with ultrasonic level meter. The merging of flow velocity with the cross-sectional area calculated. Using ultrasonic level meters can produce flow capacity or flow rate flow in the canal.
